TEHRAN, Iran (AP) _ Several police officers who allegedly led an illegal attack on Iranian university students will go on trial next week, a newspaper reported Thursday.

The raid on a Tehran University dormitory in July sparked the worst unrest in Iran in decades. The trial, which will include two top former commanders, will start Wednesday, Arya newspaper said, quoting a university statement.

The public trial is seen as an indication that hard-liners, who have just suffered a stunning parliamentary defeat at the hand of reformists, are willing to make concessions. Hard-liners control the judiciary, the police and the armed forces.

Student demonstrators had demanded a trial for those responsible for the raid, in which one person was killed and 20 injured. Some 400 students had lodged complaints with the military court against 20 policemen for illegally entering the dormitory after students protested the closure of a moderate newspaper.
