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.
