The attacker was believed to be targeting a nearby police station but struck a civilian residence before reaching the intended site, said Muhammad Sajjad Khan, a local police official. The blast caused significant casualties among residents inside the house, he added.

The death toll was confirmed by Bannu assistant commissioner Ikramullah Khan, who said the injured had been shifted to nearby medical facilities.

No group has claimed responsibility for the attack. However, suspicion is likely to fall on Tehreek-e-Taliban Pakistan, which has intensified attacks in the region in recent years, frequently targeting security installations.

Bannu lies in a volatile region bordering areas that were formerly part of Pakistan’s semi-autonomous tribal belt, long affected by militancy and counterinsurgency operations.

Pakistan has repeatedly accused neighboring Afghanistan of failing to eliminate militant sanctuaries used to plan cross-border attacks, an allegation denied by the Taliban authorities in Kabul.
