PESHAWAR, Pakistan (AP) - Suicide attackers shot their way past guards and set off a massive blast outside a luxury hotel where foreigners and well-to-do Pakistanis mixed, killing at least 11 people and wounding 70, officials said.
The bombers struck the Pearl Continental Hotel late Tuesday at about 10 p.m., when nightlife was still in swing. The attack reduced a section of the hotel to concrete rubble and twisted steel and left a huge crater in a parking lot.
The blast came a week after Taliban leaders warned they would carry out major attacks in large cities in retaliation for an army offensive to reclaim the nearby Swat Valley region from the militants. No claim surfaced immediately for the bombing in Peshawar, the northwest's largest city with about 2.2 million people.
Earlier in the day, officials said Pakistan's military engaged militants on two fronts elsewhere in the northwest. The army dispatched helicopter gunships in support of citizens fighting the Taliban in one district and used artillery fire against militants in another after sympathetic tribal elders refused to hand them over.
Neither operation was anywhere near the size of the military's offensive in the Swat Valley, where 15,000 troops have battled up to 7,000 Taliban fighters.
But the battles Monday and Tuesday in the Upper Dir and Bannu districts suggest that pockets of pro-Taliban sentiment remain strong in some areas, while the militants' form of hardline Islam is unpalatable in others - particularly because of the violence the militants have used to enforce it.
Peshawar lies in between the two districts. The Pearl Continental, affectionately called the "PC" by Pakistanis, overlooks a golf course and a historic fort. The ritziest hotel in the city, it is relatively well-guarded and set far back from the main road.
Police official Liaqat Ali said witnesses gave vivid accounts of how the bombers carried out their attack.
Three men in a pickup truck approached the hotel's main gate, opened fire at security guards, drove inside and detonated the bomb close to the building, Ali said. A senior police officer, Shafqatullah Malik, estimated it contained more than half a ton of explosives.
The chaotic scene echoed a bombing last year at Islamabad's Marriott Hotel that killed more than 50 people. Both hotels were favored places for foreigners and elite Pakistanis to stay and socialize, making them high-profile targets for militants despite tight security.
The method of attack also matched a May 27 assault on buildings belonging to police and a regional headquarters of Pakistan's top intelligence agency in the eastern city of Lahore, for which the Taliban claimed responsibility. A small group opened fire on security guards to get through a guard post, then detonated an explosive-laden van.
In Washington, two senior U.S. officials said the State Department had been in negotiations with the hotel's owners to either purchase or sign a long-term lease to the facility to house a new American consulate in Peshawar. The officials said they were not aware of any sign that U.S. interest in the compound had played a role in its being targeted.
The officials spoke on condition of anonymity because the negotiations were not public and had not been completed. They said no immediate decision had been made on whether to go ahead with plans to base the consulate on the hotel grounds.
Lou Fintor, spokesman for the U.S. Embassy in Islamabad, said there were no immediate reports of American casualties.
North West Frontier Province Information Minister Mian Iftikhar Hussain told The Associated Press early Wednesday that officials were reporting 11 deaths in the blast. Other police and government officials could confirm only five dead.
An AP reporter saw six wounded foreigners being helped out of the Pearl.
The U.N. identified a staff member as among the dead: Aleksandar Vorkapic, 44, an information technology specialist from Belgrade, Serbia, who was part of an emergency team from the office of U.N. High Commissioner for Refugees helping with the crisis.
Also killed was UNICEF staffer Perseveranda So, 52, from the Philippines, who had been working on educational programs for girls, the children's agency said.
"At the time of the bombing, the hotel was housing many humanitarian workers there to provide life-saving assistance to Pakistan's most vulnerable people. This is an attack on the very humanitarian principles to which Persy was dedicated," UNICEF executive director Ann M. Veneman said in a statement.
Peshawar district coordination officer Sahibzada Anis said the blast wounded three others working for the U.N. agency - a Briton, a Somali and a German.
Amjad Jamal, spokesman for the World Food Program in Pakistan, said more than 25 U.N. workers were staying at the hotel. He said all seven WFP workers were safe.
U.N. Secretary-General Ban Ki-moon condemned the "heinous terrorist attack" in "the strongest possible terms," U.N. deputy spokeswoman Marie Okabe said at U.N. headquarters in New York.
"Once again, a dedicated staff member of the United Nations is among the victims of a heinous terrorist attack which no cause can justify," Okabe said.
She said Ban was "saddened by the large numbers of dead and wounded" and extends his condolences to the families of the victims and to the government and people of Pakistan.
Dr. Khizar Hayat at Lady Reading Hospital said the hospital received some 70 wounded people, with at least nine in critical condition.
Farahnaz Ispahani, spokeswoman for President Asif Ali Zardari and the ruling party, condemned the attackers.
"We will not be cowed by these people," she said. "We will root them out, we will fight them and we will win. This is Pakistan's unity and integrity that is at stake."
The military offensive in Swat and surrounding districts began in late April, and officials have blamed a handful of suicide attacks on Taliban attempts to seek revenge.
