Two Russian news agencies says jailed Wall Street Journal reporter Evan Gershkovich has been formally charged with espionage in Russia and has entered an official denial. State news agency Tass and Interfax news agency said Friday that a law enforcement source informed them that Russia’s Federal Security Service officially charged the American journalist. The news outlets didn’t say in what form Gershkovich was charged or when, but generally suspects are presented a paper outlining the accusations. Russian authorities arrested the 31-year-old reporter last week. He is the first U.S. correspondent since the Cold War to be detained for alleged spying. The FSB accused Gershkovich of trying to obtain classified information about a Russian arms factory.
