Nemtsov murder: Putin urges end to political killings
Russia's President Vladimir Putin has called for an end to "shameful" political killings in Russia, after the shooting of opposition politician Boris Nemtsov just outside the Kremlin walls.
He said the most serious attention should be paid to high-profile crimes.
The former deputy prime minister, 55, was murdered on Friday night and buried in Moscow on Tuesday.
The motive is unknown, but Mr Putin's aides have rejected suggestions that he had any involvement.
Several theories have emerged for who was the behind the murder of a man who was putting together a report on Russia's involvement in eastern Ukraine:
- Opposition leader Alexei Navalny said it was either a government or pro-government organisation
- Rogue elements in the security services or fighters returning from eastern Ukraine may have wanted to silence his anti-war stance
- Or it may have been unrelated to Ukraine: Mr Navalny said it could have been ordered by officials in Yaroslavl, where Mr Nemtsov had been investigating corruption
