Nemtsov murder: Two held over killing

Two men have been detained over the murder of Russian opposition politician Boris Nemtsov, the head of the Federal Security Service (FSB) has announced.

Anzor Gubashev and Zaur Dadayev, both from the Caucasus region, were detained on Saturday, FSB director Alexander Bortnikov said.

Russian investigators said there were suspected of organising and carrying out the murder.

The killing on a bridge within sight of the Kremlin shocked Russia.

The former deputy prime minister and veteran liberal politician, 55, was shot in the back four times on the night of 27 February as he was walking on the street with his girlfriend. He was buried in Moscow on Tuesday.

That the announcement was made on state television by the head of the FSB himself is a clear sign the Kremlin wants to be seen taking this case extremely seriously, the BBC’s Sarah Rainsford reports from Moscow.
