Five US troops were killed in separate attacks in Baghdad and surrounding areas on Monday, while another soldier died of non-combat related causes, the US military said. Two US soldiers on a foot patrol southeast of Baghdad were killed when they came under attack from gunfire, the military said. A third soldier, from the Multi-National Division-Baghdad, was killed when his patrol in northern Baghdad was hit by a bomb, the military said. Four others were wounded in that attack, the military said. In a third attack, an airman was killed and three others wounded when a bomb went off at 3:55 p.m. in southern Baghdad, the military said. A Marine assigned to Multi National Force-West also was killed while conducting combat operations in Anbar province, an insurgent stronghold west of Baghdad, according to a separate statement. Another US soldier died of non-battle-related causes about 5 a.m. Monday, the military said, providing no other details. The identities of the troops were not released pending notification of relatives. The deaths raised to at least 3,399 the members of the US military who have died since the beginning of the Iraq war in March 2003, according to an Associated Press count.
