According to BBC, 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.
Anzor Gubashev and Mr Dadayev, who are both accused of organising and carrying out the murder, were bundled through a back door of the court by armed guards in balaclavas.
Little is known about the men, but reports say Mr Dadayev served in a battalion of interior ministry troops in Chechnya.
The other suspects include Mr Gubashev’s younger brother Shagid Gubashev and two men named as Ramzan Bakhayev and Tamerlan Eskerkhanov. Reports say all three have denied any involvement in the murder.
Four of the men come from the northern Caucasus region and were detained in the republic of Ingushetia which borders Chechnya, say Russian media reports.
President Vladimir Putin has condemned Nemtsov’s murder and called for an end to “shameful” political killings in Russia.
But leading opposition figure Alexei Navalny accused the Kremlin of ordering the assassination to cow the opposition amid Russia’s mounting economic problems.
Nemtsov was killed just days before a march he was organising against the war in Ukraine.
He had also been drafting a report expected to expose covert Russian military involvement in the conflict.
