It was the first time the air force has resorted to aerial strikes in the volatile region since it struck a ceasefire agreement with local Taliban chiefs in 2007. The aerial strikes also took place in the nearby tribal region of Kurram. (Agencies)
"Can you hear the noise of the gunships? They are just over our heads," Haji Jamaludin, a resident, told media over the phone.
“Everyone in the village is running around with children and women looking for a safe place to hide," he said.
Sparking speculation that a military operation was imminent, Prime Minister Nawaz Sharif cancelled his trip to the World Economic Forum in Davos on Sunday following a Taliban attack on an army convoy in which 20 soldiers were killed.
Sharif has been under pressure from United States and hawks within the Pakistani army to take tougher military action against Taliban militants.
The Pakistani Taliban is fighting to topple the government in Islamabad and impose strict Islamic rule in the nuclear armed South Asian nation. The death of Taliban chief Hakimullah Mehsud in a drone strike in November has further enraged the Taliban, with its new leader, Mullah Fazlullah, vowing to step up his campaign.
"We strongly condemn this cowardly act which they (Pakistan army) carried out under cover of darkness, targeting sleeping people," said Pakistan Taliban spokesman Shahidullah Shahid.
"If you people target innocent people in their homes, we will target you in your homes in Islamabad too," he said.
Military officials said fighter jets were targeting only militant positions in North Waziristan.
Villagers described scenes of panic as fighter jets and helicopter gunships pounded the Mir Ali area, sending villagers fleeing from their homes into the cold to hide.
There was no official word on civilian casualties and residents gave different numbers. Tribal elders said between 15 and 24 people were killed. A Taliban source put the death toll at 27. Military sources in Islamabad said 15 militants were killed.
"The jets successfully targeted hideouts of the militants involved in recent attacks on security forces and civilians in the country," said a senior official in Peshawar.
“Twenty three militants were killed and several injured," he added.
Musafar Khan, a tribesman in Haiderkhel village, said several houses had been bombed.
"We spent the night in the open with children, and others went to nearby villages because of the bombing in our village," he said.
Sharif, who came to power last year, has insisted military action was a last resort option and promised to find a negotiated solution, but the Sunday attack on the army convoy might have been the last straw.
Despite Sharif's emphasis on peace talks, attacks have continued unabated since he came to power, a worry to regional powers already anxious about security as foreign troops prepare to pull out from neighbouring Afghanistan this year.
"This (operation) hadn't been planned before, and Pakistan air force fighter jets were called to hit hideouts of the militants involved in attacks on security forces," said one military official on condition of anonymity.
Following a wave of fighter jets strikes, the army called in helicopter gunships to shell suspected hideouts. Residents said bombardment started overnight without any warning.
"We were all asleep when the planes started bombing the village," said Khyal Zaman, a tribesman from the village of Esori.
"We had no idea what happened in the dark and those who survived came out of their homes in desperation along with children and started walking away into the open," Zaman said.
It was the first time the air force has resorted to aerial strikes in the volatile region since it struck a ceasefire agreement with local Taliban chiefs in 2007. The aerial strikes also took place in the nearby tribal region of Kurram.
