Official sources said that the aircraft bombed the hideouts of militants in various areas of Upper Orakzai Agency including Bermela, Khadizai, Mamozai, Samabazar and adjoining areas destroying four hideouts of the militants.
They said that jets were sent to bomb hideouts of the militants after intelligence reports that militants from Tehreek-e-Taliban Pakistan (TTP) led by TTP chief Hakimullah Mehsud, were hiding in the mountainous region bordering Afghanistan.
Sources said that death toll may rise further as several militants were reportedly trapped under the rubble of destroyed hideouts while condition of those injured was also reported to be serious.
The political administration and official sources have also confirmed the air strikes and causalities.
However, independent confirmation of the death toll was not immediately possible as the lawless tribal region is barred for journalists.
Most of Upper Orakzai is in Taliban hands and is the scene of frequent clashes between security forces and militants while government troops are in control of its lower reaches.
A similar air strike early this month left 20 militants dead, officials said.
