LONDON (Reuters) - The murder of Boris Nemtsov drew condemnation on Saturday from leaders and politicians around the world, who paid tribute to the outspoken critic of President Vladimir Putin and Russia's role in the Ukraine crisis.

The Russian opposition leader, 55, was killed near the Kremlin. He was shot four times in the back by assailants in a white car as he walked across a bridge over the Moskva River in central Moscow, just before midnight on Friday, police said.
