Car bomb blasts kill at least 23 in Iraq

A string of car bomb blasts targeting mainly police checkpoints killed at least 23 people across Iraq on Sunday, police and hospital sources said.

No one has claimed responsibility for the attacks.

Violence in Iraq has eased since its height in 2006-07 when sectarian fighting killed thousands of people, but Sunni Islamists and an al-Qaida affiliate still launch regular attacks, seeking to undermine the Shiite-led government.
