Four coalition soldiers were injured in four explosions in central Baghdad last night.

At 20:00 local time (17:00GMT) mortars or missiles were launched at the headquarters of the US-led coalition.

Three of the injured were taken to hospital; one other was treated at the scene.

Three mortar bombs hit Baghdad’s Green Zone on Monday, according to reports.

US President George W Bush insists the US would not run from his country’s “vital mission in Iraq.”

In a separate attack on Tuesday, one US soldier was killed and two others wounded in a roadside bombing in Baghdad.
