Air raid alarms sound in Belgorod again after attacks injure 13
There have been several air raid alarms in Russia's Belgorod region Monday morning, with the regional governor warning residents to seek shelter.
Earlier, Regional Governor Vyacheslav Gladkov said on Telegram that the town of Shebekino had been attacked by a Ukrainian drone. No civilians were injured but two apartment buildings were damaged.
The latest attack, which has not been confirmed by Ukraine, comes a day after various towns in the border region of Belgorod were targeted on Sunday, leaving 13 people injured.
Belgorod has become a focal point for Ukrainian attacks on Russia's border regions; Russia says one of the main reasons it has launched a new offensive in Kharkiv, northeast Ukraine (and adjacent to Belgorod) is to create a "buffer zone" to protect its border regions.
Gladkov said Ukrainian forces attacked Shebekino with multiple-launch rockets on Sunday, injuring 11 people, including three children, and damaging apartment buildings and cars in the town. To the east of the town, the village of Rzhevka was also shelled, he said, injuring two people and damaging one house.
CNBC was unable to verify the reports and Ukraine has not commented on the attacks; it rarely does when it comes to strikes on Russian territory. Both Russia and Ukraine say they don't target civilians or civilian infrastructure.

Day of mourning declared in Kharkiv after 11 killed in spate of Russian attacks
A day of mourning has been declared in the northeast Kharkiv region on Monday after a popular leisure spot and several villages were shelled by Russian forces on Sunday, leaving 11 civilians dead and others wounded.
"May 20 is the Day of Mourning in the Kharkiv region," Oleh Syniehubov, head of the Kharkiv regional state administration, said on Telegram late on Sunday after a number of separate attacks.
"As a result of the shelling of the villages of Kivsharivka, Novoosynove [in the Kupiansk district] and the Malodanyliv community [on the outskirts of Kharkiv city], the occupiers took the lives of 11 people. Among the dead is a pregnant woman," he said.
Kharkiv has become the prime target of Russian attacks since its forces launched a new offensive in the border region on May 10.
A lakeside recreation spot in Cherkasska Lozova on the outskirts of Kharkiv city was also among the areas attacked on Sunday, leaving at least five people dead and 16 injured, Syniehubov said, among them two ambulance workers.
He accused Russia of carrying out a "double-tap" strike in which an initial attack is followed up by a second in order to kill members of the emergency services attending the scene. Russia says it does not target civilians. In a separate attack, one person was killed in Russian shelling in Vovchansk, a border town that Russian forces are believed to partially occupy.
Ukraine's President Volodymyr Zelenskyy has asked the country's Western allies to provide it with additional air defense systems to protect Kharkiv.
Commenting on Telegram Sunday, Zelenskyy said "the world can stop Russian terror - and for this the lack of political will of the leaders must be overcome. Two "Patriots" [missile defense systems] will fundamentally change the situation for Kharkiv."
