(Adds fifth death, background) BAGHDAD, March 25 (Reuters) - Five U.S. soldiers were killed on Sunday by roadside bomb attacks in Iraq, the U.S. military said in a statement. Four soldiers were killed north of Baghdad in Diyala, a restive province where U.S. commanders recently asked for more troops to fight al Qaeda and other militants. Two more soldiers were wounded in the attack. A fifth soldier was killed by a roadside bomb in northwest Baghdad, the U.S. military said. The deaths bring to at least 75 the number of U.S. soldiers killed in Iraq this month. The U.S. statement did not give any further details of the Diyala attack but commanders there have reported a rise in the occurrence of a particularly deadly type of roadside bomb called an explosively formed projectile (EFP).
