MOSCOW -- Two suspects have been detained in relation to the murder of Russian opposition leader Boris Nemtsov, the head of the Federal Security Service Alexander Bortnikov said on Saturday.
"I would like to inform you that the work that has been conducted has resulted in two suspects in this crime being detained today. They are a Gubashev, Anzor and a Dadayev, Zaur," he said in a video posted on state TV Channel One's website.
No further details were provided about the suspects, but RIA Novosti news agency quoted Bortnikov as saying that both were from the Caucasus.
Bortnikov told Channel One that Russian President Vladimir Putin had been informed of the detention and that the investigation was ongoing.
Nemtsov, 55, was shot dead near the Kremlin late on Friday as he was walking home and many European politicians and diplomats attended his funeral in Moscow on Tuesday.
The Kremlin has denied accusations that it played a role in his death.
