In Iraq, three U.S. Marines were killed today in a roadside bombing in Baghdad in the first fatal attack on US forces since the so-called handover of power yesterday. Meanwhile, another U.S. soldier, Keith Maupin, of Ohio, may have been killed by members of the Iraqi resistance. Al Jazeera has received a video purportedly of the killing of Maupin. The identity of the victim was not clear in the video. The U.S. military yesterday notified his family, but the military said it was not sure if it was Maupin that had been killed. He had been missing since mid-April. Al Jazeera did not broadcast the killing.
