Russian court extends detention of Wall Street Journal reporter Evan Gershkovich until end of January

A court in Moscow has extended the detention of Wall Street Journal reporter Evan Gershkovich, arrested on espionage charges, until Jan. 30, Russian news agencies reported.

The hearing took place on Tuesday behind closed doors because authorities say details of the criminal case against the American journalist are classified.

Gershkovich was detained in March while on a reporting trip to the Russian city of Yekaterinburg, about 2,000 kilometers (1,200 miles) east of Moscow. Russia’s Federal Security Service alleged that the reporter, “acting on the instructions of the American side, collected information constituting a state secret about the activities of one of the enterprises of the Russian military-industrial complex.”

Gershkovich and the Journal deny the allegations, and the U.S. government has declared him to be wrongfully detained. Russian authorities haven’t detailed any evidence to support the espionage charges.
