PESHAWAR: The death toll from a suicide bombing at a wedding ceremony in northwestern Pakistan rose to six, police said on Saturday, after funeral prayers were held for those killed in the attack a day earlier.

The bomber detonated explosives during a wedding gathering in the Dera Ismail Khan district of Khyber Pakhtunkhwa province, injuring more than a dozen, some of them critically.

“The death toll has surged to six,” said Nawab Khan, Superintendent of Police for Saddar Dera Ismail Khan. “Police have completed the formalities and registered the case against unidentified attackers.”

“It was a suicide attack and the Counter Terrorism Department will further investigate the case,” he continued, adding that security had been stepped up across the district to prevent further incidents.

No militant group has claimed responsibility for the blast so far.

Khan cautioned against speculation, citing ongoing militancy in the area, and said the investigation was being treated with “utmost seriousness.”

The explosion targeted the home of a member of a local peace committee, which is part of community-based groups that cooperate with security forces and whose members have frequently been targeted by militants in the past.

Some media reports also cited a death toll of seven, quoting police authorities.

Emergency officials said several of the wounded were taken to hospital soon after the blast.

Militant attacks have intensified in parts of Khyber Pakhtunkhwa since the Taliban returned to power in neighboring Afghanistan in 2021, with Islamabad accusing Afghan authorities of “facilitating” cross-border assaults, a charge Kabul denies.
