In Iraq, seven U.S. soldiers were killed when a massive roadside bomb exploded under their Bradley Fighting Vehicle killing everyone inside. The attack came in northwest Baghdad where resistance to the occupation has been particularly fierce. In a separate incident in Anbar province, two Marines were killed but the military did not release details of their deaths. It was the deadliest day for U.S. forces in Iraq since a suicide bomber struck a mess hall Dec. 21. The latest U.S. deaths came on a day that Iraq’s interim government announced it was extending martial law through Jan. 30, the date set for nationwide elections.
