Pakistani police say they lobbed tear gas and fired gunshots in the air to try to disperse an angry crowd hurling stones at the officers. The violence left one protester dead after a gunshot to the head.

The clashes erupted on Tuesday in the port city of Karachi during a demonstration over the disappearance and killing of a 7-year-old girl this week. The protesters accused police of negligence in the case.

The police also say 17 people, mostly policemen, were injured in the clashes.

Senior police officer Amir Farooq says the girl went missing two days ago and her body was found on Monday in bushes in a western Karachi neighborhood.

He says the initial forensics report suggests she was raped before being strangled.
