Two men strapped with explosives detonated themselves at Baghdad's police academy on Tuesday, killing at least 43 people and wounding 73 more, officials said. The men were wearing explosives-laden vests and a US contractor was among those wounded, a US military statement said. US forces rushed to the scene to provide assistance, the statement said. The military retracted an earlier statement that the bombers were women. "We were sitting in the yard when we heard an explosion," said police Maj. Wisam al-Heyali. "Seconds later, we were hit by another explosion as we were running. I saw some of my colleagues falling down and I felt my hand hit, but I kept on running."
