A second U.S. journalist has been detained by Russian authorities and is being held in custody.
Radio Free Europe-Radio Liberty editor Alsu Kurmasheva was charged by Russian officials Wednesday with acting as an unregistered foreign agent.
"Alsu is a highly respected colleague, devoted wife, and dedicated mother to two children," said Jeffrey Gedmin, Radio Free Europe-Radio Liberty acting president.
"She needs to be released so she can return to her family immediately," he added.
Kurmasheva was stopped and detained at the Kazan International Airport while reportedly in Russia for a family emergency on May 20.
RFE claims the Russian authorities took Kurmasheva's passport and later fined her for failing to register it with the government.

Wall Street Journal reporter Evan Gershkovich was arrested seven months ago in the city of Yekaterinburg — the first U.S. journalist detained by Russia since the Cold War.
He has made multiple court appearances appealing his confinement but has been unsuccessful thus far.
Russian authorities say Gershkovich, "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."
