A car bomb blast has killed two Iraqis and wounded 15 others, including six US soldiers, in the northern Iraqi city of Mosul.

The US military said the soldiers wounded in the explosion on Thursday were all in stable condition. There was, however, no word on the condition of the Iraqis.

"The car bomb was driven by a suicide bomber. Two Iraqi citizens were killed. Six US soldiers and nine Iraqi civilians were injured," Sergeant John Franzen said.

Mosul, home to 1.5 million people, has been witness to frequent clashes between US-led forces and their armed opponents since November.
