PESHAWAR, Pakistan (AFP) - Pakistani jets and helicopter gunships bombarded suspected Taleban hideouts in a northwestern tribal district on Tuesday, killing at least 25 people, in response to two major bombings targeting the military.
The air strikes come a day after a Taleban suicide bomber killed 13 people in a blast near army headquarters - a rare strike close to the heart of Pakistan's powerful military establishment.
The focus of Tuesday's operation was North Waziristan tribal district, a stronghold for Taleban and Al-Qaeda linked militants on the border with Afghanistan.
Military officials said the strikes were based on "confirmed intelligence reports" and some of those killed were linked to high-profile attacks including a bloody double suicide bombing on a church in the northwestern city of Peshawar in September.
Jet fighters began pounding targets around 12:30am (1930 Monday GMT), an official said, and were later joined by helicopter gunships.
A senior security official told AFP that at least 25 people had been killed.
He said some of the dead were linked to several recent bombings including the Peshawar church and an attack Sunday on paramilitary troops in northwestern Bannu city that killed 26 - the deadliest on Pakistan's armed forces in recent years.
In claiming responsiblity for the Bannu attack, the Tehreek-e-Taleban Pakistan (TTP) threatened more strikes to avenge their former leader Hakimullah Mehsud, killed by a US drone in November.
But TTP spokesman Shahidullah Shahid also said the group was "ready for meaningful negotiations" if the government halted US drone strikes and withdrew troops from the tribal areas.
The TTP have been waging a bloody campaign against the Pakistani state since 2007, carrying out a number of bomb and gun attacks, often on military targets.
The two high-profile attacks on Sunday and Monday marked a bloody return for the militants after a period of relative quiet following Mr Mehsud's death and the installation of hardline cleric Maulana Fazlullah as his replacement.
Officials said those killed in Tuesday's air raids included "foreigners" - a term that usually refers to Arab or Central Asian fighters - as well as members of the Punjabi faction of the Taleban.
An intelligence official in Miranshah, the main town of North Waziristan, said the airstrikes and shelling were still going on and had forced some residents of the area to flee.
As the military mounted their aggressive riposte to the militants, police in Islamabad said they had seized 100 kilograms (220 lbs) of explosives and arrested three people in a raid.
