Pakistan's military says soldiers killed 12 militants in recent operations targeting Taliban insurgents in South Waziristan.
The military said security forces battled militants Friday as they fought for control of Makeen - an area considered the main base of the Pakistani Taliban.
The military statement also says troops battled to tighten their control over Sararogha, which is another Taliban stronghold.
Five Pakistani soldiers were wounded in the operations.
The accounts of the Pakistan army's offensive in the tribal region near the Afghan border are difficult to verify, as journalists and aid workers are not allowed into the battle zone.
In other violence Saturday, police say two women teachers were wounded when a grenade was thrown into a school in the southwestern city of Quetta.
