At least 10 suspected militants were killed and many others injured when the Pakistan Army's jet fighters launched an air strike in the northwest tribal area of Khyber Agency on Sunday.
The jets pounded five militant hideouts in Tirah valley, along the Afghanistan border, Radio Pakistan reported.
In September 2014, the army had announced an armed offensive "Operation Khyber 1" against militants which successfully came to an end this month.
Now the military is carrying out "Operation Khyber 2" in the area and Sunday's offensive was part of it.
Talking to the media last month, Prime Minister Nawaz Sharif had said the military operations in the tribal area have broken the backbone of the militants.
