Five U.S. soldiers were killed in two separate roadside bomb attacks in Iraq on Monday, the U.S. military said, making 2007 the deadliest year for U.S. forces in the country.
The deaths took the number of U.S. soldiers killed in Iraq this year to 851, according to icasualties.org, an independent Web site that monitors U.S. troop deaths. The worst previous year was 2004, when 849 deaths were recorded.
In total, 3,854 U.S. soldiers have been killed since the U.S.-led invasion to topple Saddam Hussein in 2003.
"We lost five soldiers yesterday in two unfortunate incidents, both involving IEDs (Improvised Explosive Devices)," U.S. military spokesman Rear Admiral Greg Smith told reporters in Baghdad on Tuesday.
The military said both attacks took place in Kirkuk province near the volatile oil-refining city of Baiji, 180 km (112 miles) north of Baghdad. In the worst incident, four soldiers were killed when a roadside bomb exploded near their vehicle.
U.S. forces in Iraq say a major build-up of troops since February has helped stem sectarian violence and reduced the number of insurgent attacks on coalition forces.
Lieutenant-General Raymond Odierno, the second-ranking U.S. commander in Iraq, told a Pentagon briefing last week there had been a five-month decline in combat deaths.
Odierno said insurgent attacks had been on a steady downward trend since June, with roadside bomb blasts in particular sharply down in the last four months.
Web site icasualties said 38 U.S. soldiers were killed in October, the lowest death toll since March 2006.
The deadliest month so far in 2007 was May, when 126 U.S. soldiers were killed, and the deadliest quarter was April to June, when 331 died.
U.S. forces completed their build-up of an extra 30,000 troops in mid-June and swiftly launched a series of military operations against al Qaeda in Iraq, other Sunni Arab militants and Shi'ite militia groups around Baghdad.
Troops were moved out of their large bases into smaller combat outposts in neighbourhoods. Soldiers also went into areas previously viewed as no-go zones, exposing them to frequent roadside bomb and sniper attacks that took a deadly toll. ( Reuters )
