At least 10 people were killed and a dozen others injured when a bomb planted in a pick-up truck went off in an area in Pakistan's northwest bordering the lawless tribal belt on Monday.
The device exploded when the vehicle was in a petrol pump at Shabqadar, a town 70 km from the North West Frontier Province capital of Peshawar. The town is also located near the boundary with the Mohmand tribal region.
Women and children were among the dead and injured, TV news channels reported. The injured, several of them in a critical condition, were taken to hospitals in Peshawar.
Security forces cordoned off the area and started a search soon after the blast.
No group claimed responsibility for the attack, which occurred hours after two security personnel were killed and three more injured when a suicide bomber detonated his explosives in a bid to escape being arrested in the restive Swat valley.
The attacker blew himself up shortly after he was stopped at a check post in Mingora, the main city in Swat, last night.
This was the second suicide attack in Swat since Saturday, when six persons, including five soldiers, were killed when a bomber rammed his explosive-laden vehicle into a check post.
