Boris Nemtsov Murder
Tens of thousands of people have marched through central Moscow to honour opposition politician Boris Nemtsov, who was shot dead on Friday.Many people are blaming Putin despite his condemnation of the murder. In the last decade, at least six of Putin's political opponents have experienced violent deaths.
They carried portraits of Mr Nemtsov and banners saying "I am not afraid".
He had been due to lead an opposition march on Sunday but his killing turned the event into a mourning rally.
Mr Nemtsov's allies have accused the Kremlin of involvement, but President Vladimir Putin condemned the murder as "vile" and vowed to find the killers.
