Two suspects have been charged with involvement in the murder of Russian opposition leader Boris Nemtsov, a spokeswoman for the Moscow Court has said.
Five men have been detained over the killing of the vocal Kremlin critic, who was shot four times in the back as he crossed a bridge in Moscow last week.
One of two men charged with the murder of Russian politician Boris Nemtsov is a former senior policeman from Chechnya, Reuters reports.
Zaur Dadayev is said to have confessed to involvement in the crime.
Five men appeared in court today in relation to Mr Nemtsov's killing in Moscow. Judge Natalia Mushnikova ordered that all five men should remain in custody.
Chechen leader Ramzan Kadyrov, a Putin ally, said Dadayev, was a pious Muslim who had been angered by cartoons of the Prophet Mohammad in the French satirical newspaper Charlie Hebdo.
Kadyrov described Dadayev as "a true patriot of Russia" who had received several medals for bravery but had subsequently resigned from his interior ministry regiment for reasons the Chechen leader said were unclear.
Skepticism surrounds the suspects arrested in the Kremlin-led investigation into the death of Russian politician Boris Nemstov.
The mother of murdered Boris Nemstov's girlfriend is worried her daughter is being treated as if she had something to do with the killing.
The death of Boris Nemtsov hits particularly hard because he represented what post-Communist Russia might have become.
