Six people died on Wednesday during clashes between US troops and armed men in the northern city of Mosul.

A car chased by US military vehicles was headed towards a US-Iraqi checkpoint in Mosul when a firefight broke out, said a witness.

"The car caught fire and the four suspected insurgents inside were burnt to death, while a woman and a child bystander also were struck down," said policeman Naqib Isam Abd al-Wahid.

Another three men and women were wounded during the fight, he said.
