U.S.-led coalition air strikes reportedly killed dozens of Syrian soldiers yesterday, endangering a U.S.-Russian brokered ceasefire and prompting an emergency U.N. Security Council meeting as tensions between Moscow and Washington escalated. The 15-member Security Council met on Saturday night after Russia demanded an emergency session to discuss the incident and accused the United States of jeopardizing the Syria deal. <br/><br/>The U.S. Ambassador to the United Nations, Samantha Power, chastised Russia for the move.
