Six Americans killed...................

(Reuters) - Gunmen have killed six U.S. citizens in separate attacks since Saturday in the violent border city of Ciudad Juarez, the U.S. consulate said on Thursday, as Mexico struggles to halt surging murders. University of Texas students Manuel Acosta and Eder Diaz, who studied at the El Paso campus just across the border from Ciudad Juarez, became the latest victims when they were gunned down as they drove through the city on Tuesday. The killings followed the deaths of four other Americans, including a woman who died of multiple gunshot wounds inside a tortilla shop in Ciudad Juarez on Saturday. Two U.S. citizens died on Saturday when they came under fire in their vehicle. "Police said shooters fired 50 rounds, ... peppering the black BMW with bullets during an assault Saturday morning," the consulate said in a statement.Link
