Syria's Ja'afari blasts U.S. over air strikes

MARGARITA ISLAND, Venezuela (Reuters) - Syria's U.N. Ambassador Bashar Ja'afari said on Sunday air strikes by a U.S.-led coalition on the Syrian army that he said killed 83 soldiers and injured over 100 could not be a "technical error." Ja'afari was speaking in an interview with broadcaster Telesur on the sidelines of a summit in Venezuela. Moscow stepped up its war of words with Washington on Sunday, saying the air strikes threatened the implementation of a U.S.-Russian ceasefire plan for Syria and bordered on connivance with Islamic State.
