Police say a worshipper leaving a prayer service at a Dallas-area mosque was slightly hurt after being attacked in the parking lot by two men who fled.

Richardson police Sgt. Kevin Perlich (PER'-lik) says investigators are trying to determine a motive in Monday night's attack. He says no words were exchanged and no property was taken.

Other worshippers at the Islamic Association of North Texas scared the attackers off.

Leaders of the Council on American-Islamic Relations want the attack investigated as a hate crime.

Perlich says police are looking at all possibilities for a motive, including a possible hate crime.

The attack came a day after two men were shot and killed in neighboring Garland after opening fire outside a provocative cartoon contest featuring images of the Muslim Prophet Muhammad.
