A Russian court on Monday ordered a Russian-American journalist who was detained last week on charges of failing to register as a foreign agent to remain in custody until early December, her employer reported.

Alsu Kurmasheva, an editor for the U.S. government-funded Radio Free Europe/Radio Liberty’s Tatar-Bashkir service, appeared in a closed session in a court in the city of Kazan, the capital of the Tatarstan republic.

The radio service said the court ordered her to be held until Dec. 5, rejecting her lawyer’s request for preventive measures other than incarceration.
