Militants attacked a military base near the Afghan border Thursday, sparking a battle in which up to 30 insurgents died, the army said.
Military spokesman Maj. Gen. Waheed Arshad said nine soldiers were wounded in the fighting near Razmak, a town in the troubled South Waziristan region.
"There were repeated attacks, which were repelled. Nine of our soldiers were injured and we are hearing from local sources that militants suffered massive casualties," Arshad told The Associated Press.
He said between 25 and 30 militants were killed and the military was trying to obtain more details.
