PESHAWAR, Pakistan — A suicide bomb attack on a historic Christian church in northwestern Pakistan killed at least 78 people Sunday in one of the deadliest attacks on the Christian minority in Pakistan in years.
The attack occurred as worshipers left All Saints Church in the old quarter of the regional capital, Peshawar, after a service Sunday morning. Up to 600 people had attended the service and were leaving to receive free food being distributed on the lawn when two explosions ripped through the crowd.
“As soon as the service finished and the food was being distributed, all of a sudden we heard one explosion, followed by another,” said Azim Ghori, a witness.
The Jundullah arm of the Pakistani Taliban claimed responsibility for the bombing, the Associated Press reported. The announcement raised new concerns about the government’s push to strike a peace deal with the Taliban to end a decade-long insurgency that has killed thousands of people.
Officials of the Jundullah wing said they would continue to target non-Muslims until the United States stopped drone attacks in Pakistan’s remote tribal region. The latest drone strike came Sunday, when missiles hit two compounds in the North Waziristan tribal area, killing six suspected militants.
‘‘All non-Muslims in Pakistan are our target, and they will remain our target as long as America fails to stop drone strikes in our country,’’ Jundullah spokesman Admad Marwat told the AP.
Jundullah has previously claimed responsibility for attacks on minority Shi’ite Muslims in southwestern Baluchistan province. Hard-line Sunni extremists, including the Taliban, consider Shi’ites to be heretics.
Interior Minister Chaudhry Nisar Ali Khan, who arrived in Peshawar on Sunday evening, said 34 women and seven children were among the 78 killed. “Such an attack on women and children is against humanity,” Khan said.
Akhtar Ali Shah, the home secretary of Khyber Pakhtunkhwa province, said more than 100 people had been wounded, including 37 children.
The dead included two Muslim police officers who had been posted outside the church. Witness reported scenes of mayhem as rescue workers ferried victims from the church, which witnesses said was scattered with body parts, shrapnel, and bloodied clothing.
The bodies of 45 victims were placed in coffins and moved to the nearby St. John’s Church, where they were placed in a line in the church playground as dozens of grieving relatives and mourners gathered. The mood was somber and angry.
A large contingent of police officers was deployed outside the church, and mourners were allowed to enter the compound after a thorough security check. Ambulances were allowed to enter the compound one by one as dead bodies were placed in vehicles to take them to the morgue.
Shafqat Malik, a senior official of the bomb disposal squad, said in an interview that forensic examination of the evidence collected from the church confirmed that two suicide bombers had carried out the attack. “Each bomber carried six kilograms of explosives,” Malik said.
The attack coincided with a broader wave of attacks on religious minorities.
In March, a Muslim mob swarmed through a Christian neighborhood in the eastern city of Lahore, burning two churches and more than 100 houses. Christians also frequently find themselves accused of blasphemy under Pakistan’s strict laws.
The attacks are mostly orchestrated by Sunni extremist militant groups, although some have also been claimed by the Pakistani Taliban.
All Saints Church is one of the oldest in Peshawar and was built during the British colonial era. It is at Kohati Gate in the city’s old quarter, where numerous militant attacks have occurred in recent years, mostly targeting Muslims.
Prime Minister Nawaz Sharif has been trying to initiate peace talks with the Pakistani Taliban, aimed at ending a decade of violence. An all-parties political conference held this month gave the government approval to start negotiations with the insurgents.
But that offer was publicly rejected by the Taliban, which later claimed responsibility for the killing of a senior army general in Upper Dir, near the Afghan border, last week.
Immediately after Sunday’s bombing, questions were again raised about the government’s plans to hold peace talks.
Sharif condemned the attack. “The terrorists have no religion, and targeting innocent people is against the teachings of Islam and all religions,” he said in a statement.
The Pakistan Ulema Council, the largest clerical body, also condemned the blast, saying that the council was “standing with our Christian brothers in this tragedy.”
The opposition leader Imran Khan, who has vociferously advocated initiating peace talks with the militants, expressed solidarity with the Christian community but also repeated his call to tackle terrorism in the country.
Khan said he believed that the bombings were an attempt to the sabotage the peace talks. Syed Munawar Hasan, the leader of the Jamaat-e-Islami party, also echoed the same sentiment in a statement to local news media.
“We will take every step to ensure peace,” Khan said.
