Assad's close ally Russia, with the aid of China, has used its veto power to block any condemnations or attempts to sanction the Syrian government.The United Nations says more than 70,000 people have been killed in the war, which began as peaceful protests against Assad that turned violent when his forces tried to crush the revolt.
