Air force bombers pounded rebel positions in North Waziristan, which is one of seven tribal agencies where the al-Qaeda-linked Pakistani Taliban have strongholds.
A military official said on condition of anonymity that there were confirmed reports about the presence of the militants in the targeted areas.
"As per reports so far, 60 hardcore terrorists including some of the important commanders and foreigners were also killed in the strikes and around 30 were injured," the official said.
"There are confirmed reports that terrorists involved in recent attacks including IDP (internally displaced people) camp blast in Peshawar, IED (improvised explosives device) attacks in Mohmand and Bajaur killing innocent civilians and security forces and IED attacks at security forces convoy in NWA (North Waziristan Agency), were hiding in these hideouts," said the official.
