Pakistani fighter jets killed at least 32 people in an attack on military hideouts in the tribal region of North Waziristan on Wednesday, security officials said.
"Confirmed militant hideouts were targeted early morning today in North Waziristan through precise aerial strikes," a senior military official said on Wednesday.
"There are reports of 32 terrorists killed in strikes including some important commanders."
The official did not disclose names of the commanders killed in the strikes.
An intelligence official in North Waziristan told the AFP news agency the strikes were carried out in Miranshah, the main town of North Waziristan, and the Mir Ali, Datta Khel and Ghulam Ali areas.
There were reports of some civilian casualties, including women and children, but the security official did not confirm them.
Independent verification of the death toll is difficult as journalists are not allowed to enter the area.
North Waziristan is a known stronghold of the Taliban and other militants linked to al-Qaida.
