Four people were wounded on Saturday when shots were fired during a protest in central Pakistan over publication of cartoons lampooning the Prophet Mohammad (PBUH), police said. The shooting occurred as hundreds of protesters pelted police with stones and tried to block a road in the town of Chiniot in the central province of Punjab, a local police official told Reuters. He said it was unclear whether police or protesters fired the shots. The official said police reinforcements had been called in from neighbouring towns. "The situation is now under control". Police detained around 40 activists of the student wing of an Islamist group in the city of Multan as they tried to stage a demonstration in defiance of government's ban on public rallies in Punjab. Five people have been killed in Pakistan this week during violent demonstrations against the satirical cartoons, published in Europe, that have enraged Muslims across the world.
