Boris Nemtsov: Thousands march in memory of Kremlin critic
Thousands of people have gathered on the streets of Moscow, mourning the opposition politician Boris Nemtsov, who was murdered in what appears to be a targeted killing on Friday night in the Russian capital.
Mr Nemtsov was a fierce critic of President Putin's support for pro-Russian rebels in Ukraine, and opposition activists have accused the government of involvement in the murder - an accusation strongly denied by the Kremlin.
