Tens of thousands of people have marched in central Moscow to mourn veteran liberal politician Boris Nemtsov, whose killing has shaken Russia's beleaguered opposition.
The 55-year-old was shot as he walked on a bridge near the Kremlin with a female companion.
The killing came a few hours after a radio interview in which he denounced President Vladimir Putin's "mad, aggressive" policies and the day before he was to help lead the Moscow rally protesting over Russia's actions in the Ukraine conflict and the economic crisis at home. Mr Nemtsov's supporters claimed the Kremlin was involved, but Mr Putin condemned the murder as "vile" and vowed to find the killers.
David Cameron could face a "political problem" within his own party if he disregards a Nato target and cuts defence spending below 2% of GDP, a Conservative former defence secretary has said.
Liam Fox said many Tory MPs would find it "hard to swallow" if the Prime Minister allowed defence spending to fall below the target, while maintaining a pledge to spend 0.7% of gross national income on aid.
Ministers are under increasing pressure from Tory MPs and senior military figures to commit Britain to meeting the Nato target to spend at least 2% of GDP on defence beyond 2016.Chancellor George Osborne is reported to have warned privately that it may fall below that level.
Dr Fox warned against cutting defence spending at a time when international security is deteriorating. He told the BBC: "I think this would be a political problem inside the Conservative Party because I think that people feel that the Government's first duty is the protection of the United Kingdom and its citizens.
"And I think that we have a commitment to Nato as part of our international treaty obligations to spend that 2%."

Police said a second suspect, another teenage girl, was arrested at the biggest market in Bauchi city.
