PESHAWAR, Pakistan — Pakistan will review its relationship with the United States, the prime minister's office said, following the killing of the Pakistani Taliban leader in a U.S. drone strike.
But a top-level meeting to examine relations, scheduled for Sunday, was postponed at the last minute without explanation. Prime Minister Nawaz Sharif's office had said he would chair a meeting on the consequences for ties with Washington. There was no indication when it might now take place.
Hakimullah Mehsud, who had a $5 million U.S. bounty on his head, was killed on Friday in the northwestern Pakistani militant stronghold of North Waziristan, near the Afghan border.
The Pakistani Taliban have killed thousands of Pakistani civilians and members of the security forces in their bid to impose Islamist rule but the new government has been calling for peace talks.
The government denounced Mehsud's killing as a U.S bid to derail the talks and summoned the U.S. ambassador on Saturday to complain.
"The murder of Hakimullah is the murder of all efforts at peace," said Interior Minister Chaudhry Nisar, adding that the government still wanted to pursue talks.
Some politicians have demanded that U.S. military supply lines into Afghanistan be blocked in response to the U.S. attack.
Pakistan is the main route for supplies for U.S. troops in landlocked Afghanistan, for everything from food and drinking water to fuel, and the closure of the routes could be a serious disruption as U.S. and other Western forces prepare to withdraw from Afghanistan by the end of next year.
Pakistani cooperation is also seen as vital in trying to bring peace to Afghanistan, in particular in nudging the Afghan Taliban, who are allied but separate from the Pakistani Taliban, into talks with the Kabul government.
Relations between the United States and Pakistan have been seriously strained several times over recent years, including in 2011, when U.S. forces killed Osama bin Laden in a raid that Pakistan said violated its sovereignty.
Despite its anger, cash-strapped Pakistan depends to a great extent on U.S. support and the United States, despite frustrations over the relationship, is unlikely to ever make a complete break with its nuclear-armed ally.
Three Pakistani Taliban commanders said they had been due meet a government delegation on Saturday and they had been meeting to discuss the talks. They said they felt betrayed by Mehsud's killing and were not interested in talks.
A Pakistani Taliban spokesman vowed a wave of revenge bombings.
Allied militant groups are also planning bombings, said Ahmed Marwat, the spokesman for Jundullah militant group. The group recently killed more than 80 people when it bombed a church and is known for big attacks on civilian targets.
Mehsud's followers have been debating who should replace him while they observe three days of mourning, said Taliban spokesman Shahidullah Shahid. They have in the meantime appointed an interim leader, Asmatullah Shaheen.
Several militant commanders said on Saturday that 38-year-old Khan Said, known as Sajna, had been chosen.
But other factions of the Pakistani Taliban alliance were unhappy with the choice and were supporting other candidates, including Mullah Fazlullah, the ruthless commander from the Swat Valley, northwest of the capital, Islamabad, whose men shot and wounded schoolgirl Malala Yousafzai last year.
Even if talks started, it was unclear how successful they would be unless the government gave significant concessions to the militants, Gul said.
"You're compromising the rule of law, and ceding ground to non-state actors, giving in to a small band of criminals. It threatens everything on which Pakistan stands — the constitution, parliament," Gul said.
"They haven't thought through the consequences of these talks. They're just firefighting because they have no long-term remedy for Pakistan's problems."
While the government has been promoting talks, the powerful Pakistani military has voiced its opposition to negotiating with the al-Qaida-linked militants.
