BBC News reports: The US has responded to accusations from Pakistan that a drone strike that killed Pakistani Taliban leader Hakimullah Mehsud had destroyed the country’s nascent peace process.

A state department official said talks with the Taliban were an internal matter for Pakistan.

The statement insisted Pakistan and the US had a “shared strategic interest in ending extremist violence”.

It also said it could still not confirm that Mehsud had been killed on Friday.

Pakistan has summoned the US ambassador to protest over Friday’s drone strike that killed Mehsud.

The country’s foreign minister, Chaudhry Nisar Ali Khan, said the strike on the local Taliban leader “is not just the killing of one person, it’s the death of all peace efforts.”

It came a day before a Pakistani delegation had been due to fly to North Waziristan to meet Mehsud.

Mr Nisar accused the United States of “scuttling” efforts to begin peace talks, and said “every aspect” of Pakistan’s co-operation with Washington would be reviewed.

Information Minister Pervez Rashid said: “The US has tried to attack the peace talks with this drone but we will not let them fail.”

The US state department spokesman said: “The issue of whether to negotiate with TTP is an internal matter for Pakistan, and we refer you to the government of Pakistan for further details.”
