(QHA) -

Moscow court has extended the pretrial detention of Ukrainian film director Oleh Sentsov, who was arrested in Crimea shortly after its annexation and accused of plotting terrorist attacks.

The Lefortovo District Court ruled on September 29 that Sentsov's pretrial detention be extended until January 11, RFE/RL reports

Sentsov and three other Ukrainian citizens were arrested in May on suspicion of planning terrorist attacks in Crimea's major cities of Simferopol, Yalta, and Sevastopol.

Russia annexed Crimea from Ukraine in March after a local referendum condemned as illegal by the United States, the European Union, and the UN General Assembly.

On September 10, the chief of Ukraine's Security Service, Valentyn Nalyvaychenko, said Sentsov was on a list of people to be exchanged for pro-Russian rebels captured by Ukrainian forces in the conflict in eastern Ukraine.
