ISLAMABAD/DERA ISMAIL KHAN, Pakistan Pakistani fighter jets bombed suspected militant hideouts in an ethnic Pashtun area on the Afghan border on Thursday, killing at least 40 people, security officials said, after attempts to engage insurgents in peace talks collapsed this week.
Prime Minister Nawaz Sharif authorized the air strikes, a source in his office said - a possible sign he was finally giving in to pressure from the military for tougher military action against Pakistani Taliban strongholds.
"After restraining the army for three days, the prime minister himself authorized the strikes last night," the government official said. "It was the only option to teach the Taliban a lesson."
Sharif, who came to power last year promising to find a negotiated peace with the Taliban, has been trying to engage the militants in negotiations.
But talks broke down this week when a Taliban wing operating in the Mohmand Pashtun tribal region said it had executed 23 soldiers in revenge for the killing of their fighters by the security forces.
"At least 40 militants were killed in the precision strikes in the Mir Ali area," one Pakistani intelligence official told Reuters. "Six different locations were bombed."
Another official said among the army's targets were training camps run by Uzbek and Turkmen fighters.
Earlier, security officials had said fifteen militants were killed.
The air strikes could herald a broader military offensive in North Waziristan, a region where many al Qaeda-linked militants are based.
The morning air attacks came just hours after the army said more than 100 soldiers had been killed by Taliban militants in the last five months, a rare admission of relatively heavy casualties.
In an unusually tough statement, Sharif's spokesman said in televised remarks late on Wednesday that the army was capable of crushing all enemies.
"The prime minister wants to resolve these issues without bloodshed but if the Taliban continue killing people then we will be left with no choice but to keep our citizens safe from terrorism through any means possible," spokesman Pervez Rashid said.
