A suicide bomber targeted a funeral in northwestern Pakistan on Tuesday, killing at least 27 people.
Police said 55 other people were wounded in the explosion in the village of Shergarh in the Khyber Paktunkhwa province.
The dead included a provincial MP linked to the PTI party of Imran Khan.
He was previously associated with the Awami National Party, which controlled the province before the PTI won a majority there in May.
Imran Khan wants negotiations with the Pakistani Taliban instead of military operations against them.
The BBC reports no group has claimed responsibility for the bombing which took place during the funeral of a businessman. A witness said there were bodies and wounded everywhere.
Twenty five people died were killed on Saturday when a bus carrying women students in the south-western city of Quetta was attacked. A hospital treating the survivors was attacked afterwards.
