'Irresponsible' comments

The US has said that it would not rule out unilateral attacks in Pakistan's Afghan border areas where pro-Taliban tribal leaders have influence.

On Monday, Pakistan said that US threats of possible strikes against targets within Pakistani territory were "ill-conceived", "irresponsible and dangerous".

Tasnim Aslam, foreign ministry spokeswoman, said: "We have stated in the clearest terms that any attack inside our territory would be unacceptable.

"We do not want our efforts to be undermined by any ill-conceived action from any quarter that is inconsistent with the principles of international law and would be deeply resented in the tribal areas and generally in Pakistan."
