CCTV allegedly shows Boris Nemtsov murder
Russian TV has aired what it says is CCTV footage showing Russian opposition leader Boris Nemtsov being shot dead on a bridge in central Moscow on Friday night.
Mr Nemtsov was shot in the back as he walked home with his girlfriend within sight of the Kremlin's walls.
The grainy vision aired by Russia's state-owned TV Center network shows a wide shot of traffic crossing the Bolshoi Kamenny Bridge near the Kremlin.
Two figures identified as Mr Nemtsov and girlfriend Anna Duritskaya can be seen walking on a pavement on the far side of the bridge.
A third figure steps into view on the bridge and walks behind them, catching up just as the view is obscured by a snow-sweeping truck.
The footage then shows a figure, alleged to be the gunman, run out from behind the snow-sweeper and get into a waiting car, which then drives off.

The timestamp on the footage says the shooting happened at 11:31pm local time.
The 55-year-old Mr Nemtsov, an anti-corruption crusader and a vocal critic of president Vladimir Putin and of the war in Ukraine, was a former deputy premier in the 1990s under Boris Yeltsin.
He was shot dead shortly after giving a radio interview in which he delivered a stinging criticism of the "murderous and insane" war in Ukraine, and called Mr Putin "a pathological liar".
Tens of thousands march in Moscow to honour Boris Nemtsov
The scene where Mr Nemtsov was shot has become a makeshift shrine to his memory, covered in flowers, candles, and notes.
On Sunday tens of thousands of people rallied in central Moscow to denounce his murder and call for justice.
Organisers said 70,000 people turned out, while police estimated the crowd at 21,000.
"[Nemtsov] was a good man," said one marcher. "He was telling the truth and he was killed for the truth. And it was the Kremlin authorities who did it. And we came to express our dismay."
Russian investigators and Mr Putin have both said that the murder bears all the hallmarks of a contract killing.
Mr Putin has vowed to punish the killers, calling Mr Nemtsov's murder "vile and cynical".
But opposition politicians claim the murder may have been the work of the Kremlin, and Western leaders have called for a full investigation of the murder.
United States president Barack Obama decried the "brutal" and "vicious murder", and urged Russia to conduct an impartial probe.
Russia's Investigative Committee, which reports directly to Mr Putin, said Mr Nemtsov "might have been sacrificed" to cause instability, and said it was checking any links to the Ukraine conflict.
