At least four people have been killed and dozens more wounded in northwest Pakistan, in a suicide attack on an international airport in Peshawar province.

A VOA reporter in Islamabad said the airport was hit by rockets as well as explosives from the bomber.

The provincial minister said the militants, including a suicide bomber, were involved in the failed ground attack that followed the rocket fire.

Local media, citing an Air Force official, said the attackers were prevented from entering the complex. All were later reported dead.

A spokesman for Pakistan's national airlines said the airport was closed and all outgoing flights were canceled.

A retired military official who spoke to VOA from the scene said the rocket fire landed inside the airport complex but caused no damage. He said the attack appeared to be the work of either the Taliban or Lashkar-e-Islam militants fighting to topple the regional government.
