Bombing at police station in Pakistan kills 4

The massive explosion caused a wide swath of destruction in the town of Badh Ber, severely damaging the station and a nearby mosque and completely destroying several houses and shops.

Suspected militants have killed more than 300 civilians and security personnel in the last month in an attempt to weaken the country's resolve to continue the military operation in the tribal area of South Waziristan, where al-Qaida and Taliban leaders are believed to be hiding.

"We have to continue this war against terrorists and have to keep our nerves," said Mian Iftikhar Hussain, the information minister for North West Frontier Province where Badh Ber is located.

Police opened fire on the pickup truck as it approached a checkpoint in front of the police station, but the driver was able to detonate his explosives, said Liaqat Ali Khan, the senior police chief in the main northwestern city of Peshawar.

"The sound of the blast was very loud, and when I rushed out from my home I saw everything was destroyed here," Tariq Hasan told AP Television News. "My house was destroyed by the blast."

The attack killed four people and wounded 30 others, said Sahib Gul, a doctor at a hospital in Peshawar where the dead and injured were brought.
