At least 11 people were killed in an explosion at a checkpoint in Darazinda in northwestern Pakistan, local authorities said. They said a suicide attacker drove a vehicle packed with explosives into the post.

Accounts differ on the number of injured: local authorities reported 18, while other reports cited 30. The source report did not provide a final confirmed toll.

The attack comes amid rising violence in Khyber Pakhtunkhwa province. On September 18, an explosion and armed assault at police headquarters in Kohat killed at least 31 people, including 16 police officers.

Pakistan blames neighbouring Afghanistan for the increase in attacks; the Taliban government denies involvement. The accusations have fed armed clashes between the two countries. Pakistan has bombed border areas, saying it was targeting militants sheltering on Afghan territory.
