A suicide bomber Saturday attacked a security checkpost, in which at least 10 people were killed, in Pakistan's insurgency-hit Swat valley, a senior police officer said, Xinhua reported.
District Police Officer Qazi Ghulam Farooq said that some 25 people were also injured in the attack in the busy area of Mingora, the main city in Swat.
He said that the bomber was in an auto rickshaw and detonated his bomb near the checkpost outside the district courts.
Police said that one soldier and a policeman were among those killed in the attack near the check post jointly manned by the army and police.
No group has claimed responsibility for the attack. The police said that suspected Taliban are behind the attack.
Witnesses and officials had different versions of the attack. The army-run media center and witnesses said that the bomber was on foot and was trying to enter the premises of district courts. They said that the security personnel fired at the bomber after he refused to stop.
The checkpost was established near district courts and the area was heavily guarded and the bomber succeeded to reach the checkpost.
The injured were taken to main hospitals in the area and the people closed markets.
Witnesses said that some 25 vehicles were destroyed and several shops and roadside restaurants were damaged in the attack.
The authorities imposed curfew in the area and security forces launched a search operation to apprehend the facilitators of the bomber.
A witness said that he heard two blasts, the first small and the second was powerful. "I was 30-40 feet away from the attacks when I heard blasts and five people including a child fell on the road," the witness said.
The entire area has been cordoned off and all the shops and markets located on the road have been closed down, witnesses said.
Pakistani security forces said they have cleared most of Taliban hideouts in the restless northwest, but officials warned that militants began to launch guerrilla attacks.
On Friday, two suicide blasts hit the eastern city of Lahore, killing at least 57 and injuring over 100. The second biggest city in Pakistan ended up in a wave of panic when six back-to-back small blasts shocked the neighborhood again late Friday evening.
