At the instigation of the new Prime Minister Nawaz Sharif, a conference of Pakistan's political parties last week called for talks with the Tehreek-e-Taliban Pakistan (TTP), the main grouping of the militants.
An umbrella faction for armed Islamist outfits but also criminals and mafia gangs, the TTP was created in 2007 and pledged allegiance to Al-Qaeda. In the years since, it has carried out hundreds of attacks, killing more than 6,000 people.
The same day, the militants carried out a series of attacks in the country's restive northwest that left seven soldiers and police dead, including a general commanding an army division.
TTP spokesman Shahidullah Shahid said they had not been approached for talks and the war with the Pakistani authorities would continue unless the government announced a ceasefire.

"While it is understandable to give peace a chance through the political process no-one should have any misgivings that we would let terrorists coerce us into accepting their terms," Kayani said.
The Pakistani Taliban are made up of a myriad of factions which have declared "holy war" on the government in Islamabad, which they accuse of kowtowing to Washington, India and religious minorities such as Shiites.
Peace deals reached with the TTP in the past, in limited geographical areas, have fallen apart quickly and Pakistani media have questioned whether a genuine, effective peace agreement was really possible.
