A Moscow court has charged two men in connection with the murder of Russian opposition activist Boris Nemtsov.

It said one of the men, Zaur Dadayev, had admitted involvement in the shooting on a bridge near the Kremlin late on 27 February.

He and the other accused, Anzor Gubashev, are of Chechen origin, Russian reports say.

Three other suspects in the case also appeared before the court on Sunday and have been remanded in custody.

Nemtsov, a former deputy prime minister and veteran liberal politician, 55, was shot in the back four times as he was walking with his girlfriend within sight of the Kremlin. He was buried in Moscow on Tuesday.
