Police say security forces have raided a militant hideout in northwest Pakistan, sparking a gunbattle in which four suspected militants were killed.

Senior police officer Mohammad Sajjad says Wednesday's raid was carried out in the town of Swabi based on intelligence reports that "terrorists" were hiding in a home. He says no officers were hurt in the raid and that authorities were trying to identify the bodies of the slain men.

Sajjad says that after the raid security forces arrested 32 suspects from various areas of Swabi and that the detained men were being questioned.

Swabi is located about 100 kilometers (60 miles) northeast of Peshawar, the capital of Khyber Pakhtunkhwa province, bordering Afghanistan.
