Russian opposition leader Boris Nemtsov was shot dead in central Moscow overnight on Friday, the Russian government confirmed, according to Interfax news agency.
At least seven shots were fired at Nemtsov from a car passing by, a Russian investigative committee spokesman was quoted by Interfax.
The agency also quoted a source as saying the opposition leader's killing "appears to be contract killing."
Russian President Vladimir Putin condemned the murder of Nemtsov and said it may have been a contract killing, Russian news agencies quoted his spokesman as saying early on Saturday.
Dmitry Peskov said the shooting late on Friday in Moscow could also be a "provocation" - the opposition plans a big protest in Moscow on Sunday.
He said Putin had been quickly informed of the killing and that the president had expressed his condolences and ordered the security agencies to investigate.
