Senior political leader Imran Khan, whose Pakistan Tehrik-e-Insaf party rules the northwestern Khyber Pakhtunkhwa province, has warned that the provincial government might stop NATO supplies from Monday.
The province is the major supply route for NATO forces in Afghanistan.
A Taliban spokesman, Azam Tariq, said Saturday the militants could not hold talks when their leaders were being killed. He also warned of revenge attacks.
Officials say Pakistan's ambassadors in the capitals of the five permanent members of the UN Security Council would brief the host governments on the negative consequences of the drone attack to the peace process.
