Pakistani fighter jets have pounded militant hideouts in the country's northwest, killing at least 37 suspected militants.
Military sources told reporters the early morning strikes in the Khyber tribal region were carried out after intelligence reports showed that the "terrorists" involved in recent attacks in Pakistan were hiding in the area.
No independent confirmation of the the military's claim was immediately available.
The airstrikes come just days after the Pakistani Taliban, Tehrik-e-Taliban, announced it will not renew a ceasefire that began on March 1. During the cease-fire, militant violence appeared to be reduced, with government negotiators and Taliban leaders taking part in one round of direct talks.
Elsewhere in Pakistan, officials say a suicide bomber killed a senior police officer and three other people Thursday in Karachi.
No one claimed responsibility for the attack that took place near a vegetable market in the southern port city.
Police officials say the slain senior officer, Shafiq Tanoli, actively targeted militants and had survived previous assassination attempts.
