This was CNBC's live blog tracking developments on the war in Ukraine.

Russian crowds are flocking to see a new exhibition in Moscow of NATO military hardware that was captured by Russian forces in Ukraine.

The display features a range of "trophies," ranging from U.S.-made armored fighting vehicles to state-of-the-art tanks and European armored personnel carriers, from 12 countries including the U.S., U.K., France, Sweden, South Africa, Turkey, Australia and Germany.

In other news, Russia appears to be looking to bolster the combat strength and weapons supplies of its forces ahead of an expected new large-scale offensive in mid-May, early June.

Russian Defense Minister Sergei Shoigu commented Wednesday that to maintain the pace of current offensive operations and ahead of "further actions," more weapons and military equipment needed to be sent to the front lines.

In the meantime, Russian forces appear to be shifting their operational focus on to Chasiv Yar, a key strategic target as they look to occupy more territory in Donetsk, in eastern Ukraine.

Two killed in Russian shelling in Donetsk

Two people were killed and six more were injured on Wednesday following Russian shelling of the city of Hirnyk, according to the head of Donetsk's regional state administration.

In a Telegram post, Vadym Filashkin said the attack had occurred during the afternoon, local time, and that final information on the number of victims and the full extent of the damage was yet to be established, according to an NBC translation.

CNBC was unable to independently verify the report.

UAE faces pressure over Russian trade

The United Arab Emirates is facing fresh pressure from the U.S., U.K. and European Union to show it is clamping down on Russian sanctions evasion, Reuters reported Thursday, citing sources familiar with the matter.

Allied officials have repeatedly asked the UAE to share trade information on its exports to Russia, as well as the re-export of dual-use goods, which have both military and civilian applications, the sources said.

The UAE's foreign ministry told CNBC that bans on certain dual-use products "deemed essential in mitigating the conflict in Ukraine" had been issued, but added that early data suggested there had been no export or re-export of such goods this year.

"The UAE strictly abides by UN sanctions and has clear and robust processes in place to deal with sanctioned entities, which we have exercised against a number of companies since the beginning of the conflict. We remain in close dialogue with our international partners, including the US and EU, concerning the ongoing conflict in Ukraine and its implications for the global economy," a spokesperson added in a statement.

Russia claims it's attacked Ukraine's southern command headquarters in Odesa

Russia's defense ministry claimed on Wednesday that it had struck the command headquarters of the Ukrainian army's southern grouping in Odesa.

"Operational-tactical aviation, missile forces and artillery from groups of forces of the Armed Forces of the Russian Federation hit headquarters of the operational command of the Armed Forces of Ukraine 'South'," the defense ministry said in a post on Telegram translated by NBC News.

It provided no further details on the damage caused but Ukraine's Southern Command confirmed that an attack had taken place overnight.

"Continuing their terrorist actions, the enemy on the night of May 1 launched another strike on Odesa with ballistic missiles from the territory of temporarily occupied Crimea. As a result of the hit, administrative and residential buildings, medical and educational institutions were destroyed," it said on Facebook Wednesday.

CNBC could not independently verify the accounts from either side.

Odesa has come under frequent fire of late. On Monday, six people were killed and 32 injured when a Iskander ballistic missile equipped with a cluster munition warhead struck a busy seafront area in the southern port city.

Russia shows off NATO military hardware captured in Ukraine

An exhibition of Western military hardware captured by Russian forces in Ukraine has gone on display in Moscow.

The display, which opened to the public on Wednesday, shows off hardware donated to Kyiv by its NATO allies, including German and U.S.-made tanks and armored vehicles displaying national and NATO flags.

"The exhibition presents various examples of seized military equipment which were captured by Russian servicemen in the special military operation zone. In all, there are 32 items [or various armored equipment]," Andrey Lyubchikov, senior researcher with Russia's Central Armed Forces Museum, told Russia's TASS news agency.

The hardware, which is on display at the Victory Museum on Poklonnaya Hill in Moscow, features a German-made Leopard 2 tank, an American Abrams tank, a Bradley fighting vehicle and armored vehicles including the U.S.-made М113 and MaxxPro, a Turkish-made BMC Kirpi, a U.K.-made Mastiff and a CV90 combat vehicle from Sweden, "as well as many others captured by the Russian servicemen during the special military operation," TASS reported.

The exhibition also displays firearms, documents, maps, gear and drones, TASS noted.

Both Russia and Ukraine have both relished displaying military hardware that they've captured from each other over the course of 25 months of war. Kyiv has a selection of Russian tanks on display in Kyiv.

Moscow's latest exhibition comes ahead of Russia's "Victory Day" on May 9, when the country commemorates the Soviet victory over Nazi Germany in World War II.

Russian forces repeat attacks on targeted northeastern region

Russian forces launched more air strikes on the northeastern Ukrainian region of Kharkiv, officials said Wednesday.

"A detailed inspection of the landing site revealed damage to ten private households. At the moment, there are no casualties or injuries," he said on Telegram, according to a Google translation.

The wider Kharkiv region was also attacked on Wednesday morning, said Oleh Syniehubov, the head of the Kharkiv regional military administration.

"About 15 settlements of the Kharkiv region were hit by enemy artillery and mortar attacks," he said in a Google-translated post on Telegram.

Syniehubov said that a man and woman were killed when the car they were in was shelled in the village of Zolochiv, to the northwest of Kharkiv city. Two others were wounded.

CNBC was unable to immediately verify the information in the officials' posts.

At least two people were killed and six were injured in a Russian strike on Kharkiv city on Tuesday, with 18 other settlements in the region also targeted with artillery and mortar attacks.

Russia has signaled that capturing the city is a key military objective in a forthcoming large-scale offensive. Moscow wants to create a so-called "sanitary zone" of occupied territory in order to protect its border regions from Ukrainian attacks.

Russian defense minister corruption scandal could taint others, UK says

A bribery investigation into Russian Deputy Defense Minister Timur Ivanov is likely to touch the higher echelons of Russia's government, the U.K.'s Ministry of Defense said Wednesday.

The investigation into Ivanov, who is accused of accepting a large bribe while in office, "has likely pulled in the more senior First Deputy Defence Minister Ruslan Tsalikov," the ministry said in an intelligence update on social media platform X.

"It has been reported that Tsalikov has been questioned by the FSB in connection with the Ivanov case. Tsalikov has been described as a patron of Ivanov. Tsalikov is likely effectively number three in the Ministry of Defence hierarchy, after Defence Minister Sergey Shoygu and Chief of the General Staff General Valery Gerasimov," the update added.

Ivanov denies the charges, but has already been fired by Defense Minister Sergei Shoigu, a source told Russian state news agency Tass. Two other suspects were arrested in relation to the inquiry: Alexander Fomin, the co-founder of a construction company, and Sergei Borodin, a close associate of Ivanov.

They have not commented on the matter.

There is also "a realistic possibility" that investigations into Ivanov could also affect Russian Finance Minister Anton Siluanov, the U.K.'s defense ministry said. It noted that some sources had claimed that defense ministry-linked construction agencies built a house for Siluanov.

"Corruption has long been a problem in the Russian MOD," the U.K. said, signaling that it was also a factor in "Russia's poor performance particularly early in the Ukraine conflict, where corruption was blamed for expired ration packs and poor-quality tyres, and fuel embezzlement was also reported."

Tear gas, water cannons, stun grenades: Police crack down on protests against controversial law in Georgia

Police used tear gas, stun grenades and water cannons against protesters in Georgia's capital Tbilisi on Tuesday night as demonstrations over the so-called "foreign agent" bill escalated.

The bill would force non-governmental organizations, campaign groups and media platforms who receive at least 20% of funding from abroad to register as "foreign agents."

The bill's opponents say the bill would obstruct media freedom, and push the country away from the European Union and closer to Russia. The U.S. State Department has said it is "akin to the kinds of legislation that we see in the Kremlin."

Ukraine launches drone attacks on several Russian regions, officials say

Ukraine launched drones on several Russian regions in hours leading to Wednesday morning, Russian officials said, with unofficial Russian news outlets reporting a fire at the Ryazan oil refinery after the attack.

Pavel Malkov, governor or the Ryazan region, which shares a border with the Moscow region in its northwestern parts, said that there were no injuries in the drone attacks there.

Russian Telegram channel Baza, which is close to the security services, reported that the attack sparked a fire at the Ryazan oil refinery.

The refinery, owned and run by Rosneft, refines about 5.8% of Russia's total refined crude. It has been a frequent target for Ukraine's air attacks.

The governors of the Kursk and Voronezh regions in southwest Russia that border Ukraine also reported drone attacks on their territories, saying there was no damage or injuries.

Russia rarely discloses information about the full impact of Ukraine's attacks on its territory and infrastructure.

Kyiv officials say targeting Russia's military, energy and transport infrastructure undermines Moscow's war effort. Reuters could not independently verify the Russian reports.

Russia could be shifting focus onto strategic target, Chasiv Yar

Russian forces appear to be shifting their operational focus on to Chasiv Yar in the northern area of Donetsk, in eastern Ukraine.

Russia did not make any confirmed advances in the Avdiivka area for the first time in several days on Tuesday, analysts at the Institute for the Study of War noted, while Ukrainian sources reported that Russian forces conducted several more attacks in the Bakhmut-Chasiv Yar direction in recent days than around Avdiivka, in central Donetsk.

"The Ukrainian General Staff's reports on Tuesday stated that Ukrainian forces had repelled a total of 47 Russian attacks in the Avdiivka direction and 57 Russian attacks in the Bakhmut direction throughout the day, notably a much higher number of attacks in the Chasiv Yar direction than Ukrainian sources have recently reported," the Institute for the Study of War noted Tuesday.

"One day's worth of reporting is not sufficient to establish a pattern, but it may suggest that Russian forces are somewhat slowing down the rate of attacks around Avdiivka while re-committing to offensive pushes around Chasiv Yar, as ISW recently forecasted they would," ISW analysts said.

The apparent shift in focus suggests Russians are concentrating forces in the area ahead of an attempt to seize Chasiv Yar, a town that's seen as a key target for Russian forces because it lies on strategic higher ground and is seen as a gateway to advancing on the so-called "fortress belt" of Ukrainian-held cities in Donetsk, including Kramatorsk and Sloviansk.

"Chasiv Yar is an operationally significant objective as it would provide Russian forces with a staging ground to launch offensive operations against Druzhkivka and Kostyantynivka, which form the fortress belt of four major cities in Donetsk Oblast [region]," ISW analysts said.

Russia looks to beef up weapons, forces ahead of new offensive

Russia appears to be looking to strengthen the weapons supplies and combat strength of its forces ahead of an expected new large-scale offensive in mid-May, early June.

Russian Defense Minister Sergei Shoigu commented Wednesday that to maintain the pace of current offensive operations and ahead of "further actions," more weapons and military equipment needed to be sent to the front lines.

"To maintain the required pace of the offensive and ensure the build-up of the combat strength of troop groups for further actions, it is necessary to increase the volume and quality of weapons and military equipment supplied to the troops, primarily weapons of destruction," Shoigu said, according to a Google translated report by RIA Novosti.

Speaking at a meeting at the headquarters of the Joint Group of Forces, Shoigu also reportedly noted that troops "continue to carry out tasks in operational directions in accordance with the plan for the special military operation," as Russia still calls its war against Ukraine.

Russia is widely expected to launch a new offensive against Ukraine in mid-May or June with the capture of Chasiv Yar, west of Bakhmut, seen as a key target in the eastern Donetsk region where fighting remains at its most intense.

Russia's defense ministry claimed earlier this week that its forces had seized two more villages to the north and northwest of Avdiivka, building on recent advances near the industrial city that they seized in February.

Estonia accuses Russia of violating international rules with GPS interference

Estonia, which shares a nearly 300-kilometer-long (182 miles) border with Russia, accused Moscow of violating international regulations by interfering with GPS signals and affecting civil aviation in the region.

Finnair on Monday said it had temporarily suspended daily flights to Tartu in eastern Estonia "so that an alternative approach solution that doesn't require a GPS signal can be put in place at Tartu Airport."

The Finnish airline said in a statement that two Finnair flights en route to Tartu had to be diverted back to Helsinki last week after GPS interference, which it said was "quite common" in the area.

Estonian Foreign Minister Margus Tsahkna on Monday accused Russia of GPS interference in Estonian airspace that had affected civil aviation in the region. He did not provide any evidence to support his claim.

Tsahkna added via social media platform X that he intended to address the issue with NATO allies and European Union member states.

A spokesperson for Russia's foreign ministry was not immediately available to comment when contacted by CNBC on Tuesday.

Russia says it shot down U.S.-supplied ATACMS missiles

Russia said it shot down six U.S.-supplied long-range missiles, known as Army Tactical Missile Systems, or ATACMS, over the past day.

In a Google-translated update on Telegram, Russia's defense ministry said that air defense systems had, in the past 24 hours, "shot down ... six ATACMS operational-tactical missiles made in the USA." It added that Ukrainian drones and French-made "Hammer" guided bombs had also been shot down.

The ministry did not provide evidence for the claim.

The U.S. has quietly supplied the long-range missiles to Ukraine in recent weeks, enabling Kyiv to strike Russian military targets up to 300km (190 miles) away. It's uncertain how many ATACMS missiles Ukraine was given. The missiles were used for the first time in mid-April, when a Russian airfield in Crimea was targeted. Ukraine has not commented on the latest attack.

Russia's defense ministry did not say where the ATACMS missiles were shot down, but the Russian-installed head of Crimea, Sergei Aksyonov, commented in a Google-translated post on Telegram that ATACMS missiles were neutralized over the peninsula that Russia has occupied since 2014.

"After the ATACMS missiles were shot down, the undetonated submunitions scattered," he said, warning civilians not to touch or approach any unspent submunitions.

Odesa attack being investigated, Ukraine's prosecutor general says

A Russian attack on Ukraine's southern port city of Odesa is being investigated, Ukraine's Prosecutor General Andrii Kostin said Tuesday.

Five people died in the attack on a busy seafront park, and 32 others were injured, with the majority of them still receiving treatment in hospital Tuesday.

Kostin said in a statement on X that by seemingly targeting civilians in the strike, Russia "cynically disregards all norms of international humanitarian law."

"Yesterday evening, in the enemy's insidious attack on Odesa, five people were killed and over 30 injured. Among the wounded are two children and a pregnant woman. Five of the hospitalized are in critical condition."

"The strike was carried out with an Iskander ballistic missile equipped with a cluster munition. This is an indiscriminate weapon, the use of which can lead to significant civilian casualties. Metal fragments and missile debris were recovered within a 1.5 km radius from the attack site," he said.

The investigation has grounds to believe that Russian forces officers decided to use this particular weapon "deliberately to kill as many Ukrainian civilians as possible," Kostin said.

The investigation is ongoing, he said, pledging to hold those responsible to account. Russia denies deliberately targeting civilians.

Russia likely used ballistic missile with cluster warhead in Odesa attack, official says

Russian forces used an Iskander missile armed with a cluster warhead to carry out the deadly strike on a crowded seaside area of Odesa on Monday, an official said.

Dmytro Pletenchuk, a spokesperson for Ukraine's Southern Defense Forces, told national media late Monday that early information suggested Russia had targeted the area with an Iskander-M ballistic missile equipped with a cluster munitions warhead.

"Preliminarily, that it was an Iskander, preliminarily a cluster one. But until all relevant expert measures are taken, I will not say 100%. However, judging by the holes on the walls, it had just cluster munitions inside, such as shrapnel, and the detonation was airborne," he said, according to the Ukrainian News Agency.

He noted that cluster bombs were primarily used to hurt civilians rather than infrastructure, noting, "as you can see, Russians see civilian residents of the city of Odesa ... as a military force."

CNBC was unable to verify the information commented on by Pletenchuk.

Five people were killed and a further 32 injured — some seriously — in an attack on the seafront park in Odesa Monday. The attack came when many people were enjoying the park after work or walking their dogs, officials said. A local landmark, a law academy, was seen on fire with its roof missing.

Russia denies deliberately targeting civilians in the war against Ukraine. Both Russia and Ukraine have used cluster munitions in the conflict. The weapons are controversial as they're known to pose a high threat to civilians.

Five dead and many injured in Russian missile strike on Odesa

A day of mourning has been declared in the Ukrainian port city of Odesa after a Russian missile strike killed five people and left 32 other injured.

The Russian strike hit a popular seafront park where many people were relaxing or walking their dogs after work, officials said. A law academy building was pictured on fire after the attack.

"The Russians hit one of the most popular locations among Odessa residents and visitors with a ballistic missile, previously with a cluster munition, where people walked with children, dogs, played sports...
Such munitions are used to kill manpower and pose a threat primarily to people, not for machinery and buildings," Oleg Kiper, the head of the Odesa regional military administration, said on Telegram.

In an update Tuesday, Kiper said a number of people remain in a serious or extremely serious condition in hospital.

Gennadiy Trukhanov, Odesa's mayor, described the attack as deplorable on Telegram: "Inhumans target peaceful people who were just resting after a day's work. Walked with small children. With pets. There are no words that can express our attitude towards those creatures that bombard our cities. Russia is a terrorist country."

Russia says it does not deliberately target civilians in the war against Ukraine, although thousands have died in attacks on residential and civilian infrastructure since the war started in February 2022.
