A 122 mm rocket slammed into a mess tent at a military base near the northern city of Mosul, ripping through the ceiling and spraying shrapnel as U.S. soldiers sat down to lunch. Officials said 22 people were killed in the deadliest single attack against Americans in Iraq since the start of the war. The dead from Tuesday's attack included 20 Americans _ 15 service members and five civilian contractors _ and two Iraqi soldiers. Sixty-six people were wounded, including 42 U.S. troops, Capt. Brian Lucas, a military spokesman in Baghdad, said early Wednesday.
