Baghdad: Two suicide car bombings killed at least 14 people in northern Iraq on Tuesday in attacks targeting a local police chief as well as an anti-Al Qaida tribal leader.

Al Qaida in Iraq had vowed increased attacks during the Muslim holy month of Ramadan to target government officials and tribal leaders allied with the United States.

Police said one car bomb targeted a mosque in Baiji, north of Baghdad. Ten civilians were killed and 22 others wounded in the blast.

The other attack was aimed at Baiji's police chief, Colonel Saad Nifous, who was wounded in a blast at his home that killed four of his bodyguards and wounded seven.

A police source said the target of the mosque bombing was Hamad Al Jubouri, the Sunni Arab leader of the "Awakening" council for Salahuddin province. It was unclear if Jubouri was hurt.

In two other attacks in the north on Tuesday, the deputy police chief of Nineveh province was killed by gunmen in Mosul and the head of police intelligence in Kirkuk was wounded in a drive-by shooting, police sources said.

The attacks came as Iraq's feuding leaders were working to pass laws aimed at reconciling majority Shiites and minority Sunni Arabs in the government.
