A Sunni lawmaker says he escaped an assassination attempt when gunmen ambushed his convoy north of the Iraqi capital.

Falah al-Naqeeb, a member the Sunni-backed Iraqiya parliament bloc, said over the phone on Tuesday that gunmen sprayed the cars with bullets in the Sunni-dominated area of Taji, about 12 miles (20 kilometers) from Baghdad.

Al-Naqeeb says no one in his convoy was hurt and demanded the government investigate the Monday night attack.

A police officer confirmed the attack. He spoke on condition of anonymity because he is not authorized to speak to the media.

The attack is the latest report of violence as political tensions are growing amid a power struggle between the Shiite-led government and Sunni politicians.
