KIRKUK - Six blasts targeting Shi'ite mosques in the disputed Iraqi city of Kirkuk killed at least eight people and wounded 67 during prayers on Friday, police and hospital sources said.

The attacks were the latest in a wave of attacks apparently launched to stoke sectarian tensions and challenge the country's Shi'ite Muslim Prime Minister Nuri al-Maliki.

The government is still struggling to overcome a stubborn insurgency eight months after US troops left.

Two roadside bombs exploded outside the Imam Ali Husseiniya in the city, while one roadside bomb and one car bomb each detonated outside both the Khazaal Al-Timimi Husseiniya and the Al-Mustafa Husseiniya. A 'Husseiniya' is a Shi'ite mosque.

Buildings and cars near the blasts were damaged and corpses lay in the streets, a Reuters witness said.
