Nine people have been shot dead at an electronics store in the Iraqi capital, Baghdad.
They were killed by gunmen wearing the uniform of Iraqi police commandos.
Police said six people were wounded by the attackers, who pulled up at the store in the west of the city in three civilian cars and then ran into the store and opened fire.
Separately, the US military has said that two of its soldiers were killed and three wounded in separate attacks in Iraq yesterday.
One US soldier was killed and three were wounded when a roadside bomb hit their vehicle outside Habbaniya, near Falluja, 50km west of Baghdad.
Another US soldier was shot dead just south of Baghdad.
