At least 200 Russian journalists have signed an open letter calling on the Russian government to release American journalist Evan Gershkovich after he was detained and charged with espionage last week. The letter’s authors compared Gershkovich’s espionage case to that of Russian defense reporter Ivan Safronov, who was last year found guilty of treason and sentenced to 22 years in prison, in a case that his supporters allege was brought against him as punishment for his journalism. Gershkovich on Monday appealed against his detention, which is scheduled to last until at least May 29
