Rocket attack at airport

At least four people have been killed and more than 20 wounded in a rocket attack at a regional airport in Pakistan.

The attack happened at Peshawar airport in northwest Pakistan on Saturday.

Peshawar is located on the edge of Pakistan's tribal region, the major sanctuary for al-Qaida and the Taliban.

A BBC correspondent said three rockets landed in residential areas close to the airport.

The airport is used as a base by the Pakistan Air Force as well as for commercial flights.

The air force said in a statement there were no casualties among service personnel or damage to equipment.

Peshawar has witnessed many bombings and shootings in recent years, but such large attacks at the airport are rare.
