One soldier died from wounds received in a mortar attack on his unit on Friday, while the other died of bullet wounds sustained in a sniper ambush the same day, a US military  statement said.

On Friday, a military vehicle overturned during a patrol, killing a soldier, the military said.

It is reported that 775 US service members have died since the beginning of military operations in Iraq last year, according to the Department of Defence. Of those, 565 died as a result of hostile action and 210 died of non-hostile causes.

It was unclear whether the latest deaths were included in the Department of Defence toll.

A US military spokesman said recently US occupation forces faced in Iraq as many as 50 attacks a day with rocket-propelled grenades, assault rifles or mortars.
