At least seven people including four policemen were killed and dozens more were injured Saturday in a suicide bombing in Pakistan's north-western valley of Swat, dpa reported.
The bomber rammed an explosive-laden car into the outer wall of a police station located in a busy market of Charbag area.
"The explosion was so huge that it partially damaged around 40 nearby houses and shops," said a security official, who spoke on condition of anonymity.
"Four policemen and three civilians died in the bombing," he said.
Malik Naveed, the police chief of the North-Western Frontier Province confirmed only the deaths of two policemen and said five more were injured.
Thirty-six people were injured in the attack, according to an official at the district hospital in Saidu Sharif.
"Among the injured are 28 civilians and eight policemen," he said.
He added the death toll could rise because half a dozen of the victims were in critical condition.
