the no-peace process...
Pakistan's interior minister has said the death of Pakistani Taliban leader Hakimullah Mehsud has destroyed the country's nascent peace process.
"This is not just the killing of one person, it's the death of all peace efforts," Chaudhry Nisar Ali Khan said.
Pakistan summoned the US ambassador to protest over Friday's drone strike that killed Mehsud.
It came a day before a Pakistani delegation had been due to fly to North Waziristan to meet Mehsud.
Hakimullah Mehsud was killed a day before Pakistani officials say they were scheduled to send a three-member team to start peace negotiations with the Taliban.
Pakistan's Interior Minister Chaudhry Nisar Ali Khan told a local TV news channel, Geo, that the drone strike was an attempt to "sabotage" Pakistan's peace talks with Taliban.
But many believe Mehsud's death will leave the field open for groups that are known to have publicly favoured a rapprochement with Pakistan.
One of these groups is headed by Khan Said Sajna, the successor of Waliur Rehman, a militant commander who favoured talks with Islamabad and once contested the leadership of the Pakistani Taliban. Rehman was killed in a drone strike in May.
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."
Pakistani Prime Minister Nawaz Sharif had pledged to talk with the Taliban to try to end its campaign of violence, which has left thousands dead in bombings and shootings across the country.
