Russia has repeatedly blocked efforts towards a UN resolution that could pave the way for intervention in Syria's 10-month crackdown on protesters.

Western countries accuse Russia, which continues to sell heavy weapons to its close Arab friend, of failing to "uphold human rights" by backing the government's military offensive, which has claimed thousands of civilian lives across the country.
