The death toll from a bombing at a wedding near the Afghan border rose to seven on Saturday, police said, as Pakistan struggles to deal with a rising wave of attacks.
The bombing tore through a building housing members of a peace committee during a wedding ceremony on Friday in northwestern Pakistan's Dera Ismail Khan district, said police official Muhammad Adnan.
The committees are made up of local residents and elders and supported by Islamabad as part of its efforts to counter rebels in the regions along the Afghan border.
The four, who were among nearly a dozen people hurt in the attack, died in the hospital, Adnan added. Three people were confirmed dead on Friday.
No group has claimed responsibility for the bombing.
