Six US soldiers were killed and two others wounded in insurgent attacks in Iraq, the US military said on Thursday.

Four Task Force Lightning soldiers died of wounds sustained in a roadside bomb attack while conducting combat operations in volatile Diyala province in eastern Iraq on Wednesday, the military said in a statement.

Two more soldiers were wounded and taken to combat medical facility, the statement added.

Separately, a Multi-National Division - Baghdad soldier died of wounds Wednesday, one day after being shot by insurgents' small arms fire while his patrol was providing security around a roadside bomb they discovered during a combat patrol north of the Iraqi capital, the military said in another statement.

Another Task Force Lightning soldier died Tuesday in a noncombat incident, a military statement said, without specifying where and how the soldier died, adding that the incident is currently under investigation.

About 3,130 US soldiers have been killed in Iraq since the US-led war on Iraq broke out in March 2003, according to media count based on Pentagon figures.
