BAGHDAD, Iraq - Two suicide bombers tried to drive explosives-laden trucks into a Polish-run base south of Baghdad, but coalition forces opened fire, triggering blasts that killed at least 11 Iraqi civilians and wounded dozens, including more than 30 coalition soldiers, officials said. More than 64 people were injured in the blasts, including at least 31 Iraqis, 12 Filipinos, 10 Poles, 10 Hungarians and an American, officials said. Polish Gen. Mieczyslaw Bieniek, commander of the 9,500-strong Polish military contingent, called it a "well coordinated terrorist attack."
