伊拉克北部自杀爆炸12人丧生

Suicide bombers have detonated cars packed with explosives in northern Iraq, killing 10 people in Kirkuk and two others in the town of Tuz Khurmatu.

In Kirkuk, officials say the blast Wednesday happened outside the offices of the Kurdistan Democratic Party. More than 100 people were wounded.

There was no immediate claim of responsibility for the attacks, which come amid heightened ethnic and sectarian tensions in Iraq.
