PESHAWAR, Pakistan (Reuters) - A suicide car-bomber killed four people on Monday near a Pakistan air force base close to the northwestern city of Peshawar and the Afghan border, a government official said.

The city has been targeted several times since the army began an offensive against the Taliban in South Waziristan last month and militants stepped up retaliatory attacks. Hundreds of people have been killed.

The attacker set off his bomb after being challenged at a checkpost near a police station about 2 km (1 mile) from the Badaber air base on the city's outskirts. The blast badly damaged the police station, a mosque and a shop.

"It was a suicide car-bomb attack. The mosque was worst damaged. The police station was also damaged," city administrator Sahibzada Anis told Reuters.

Four people were killed and 24 wounded, said Abdul Hameed Afridi, administrator at the Peshawar's main hospital.

The bomber was driving a small van of a type often used as a delivery vehicle and police opened fire on him when he refused to stop for a check, said Peshawar police chief Liaquat Ali Khan.

The van was coming from the direction of the Khyber ethic Pashtun tribal region where Taliban militants have been fighting security forces.

"We have beefed up checks at entry and exit points to and from the tribal areas and that's why these blasts are taking place at our checkposts and our men are laying down their lives," Khan told Reuters.
