The U.S. military in Iraq says it has arrested six men who are suspected of shooting down a civilian helicopter earlier this week that resulted in the deaths of 11 foreigners.
Officials say a civilian tip led to the arrests during overnight raids of two houses. Bomb-making material was also confiscated. The military did not say where the houses were located nor did it give the suspects' nationalities.
The helicopter was shot down Thursday north of Baghdad. Two militant groups have claimed responsibility for the attack and have released video footage of it.
Meanwhile, at least 12 Iraqis were killed and dozens injured in three separate explosions on Saturday in Baghdad and to the south, near Basra. An American soldier was also killed in a blast south of Baghdad. And the Associated Press reports gunfire killed one of its cameramen, Saleh Ibrahim in Mosul.
