Islamabad: At least 35 suspected terrorists were killed when military planes shelled their hideouts in Pakistan's North Waziristan Agency Sunday.

According to the Inter-Services Public Relations (ISPR), the air strikes were conducted in Dattakhel tehsil, Dawn reported.

The conflict zone is off-limits to journalists, so there is no way to independently verify the number and identity of those killed.

Officials said that over 1,200 suspected militants had been killed since the army launched Operation Zarb-i-Azb in North Waziristan in June 2014.

The administration lifted curfew from the area after 20 days Friday.
