A suicide bomber on Sunday killed a Pakistani provincial minister and at least nine other people at a building where the minister was holding a meeting, officials said.

"Punjab Home Minister Shuja Khanzada has embraced martyrdom," chief rescue official Mohammad Ashfaq told AFP.

Saeed Illahi, adviser to the province's chief minister, confirmed Khanzada's death.

He had been trapped with several others under the rubble after the blast brought down the roof of the building in the village of Shadi Khan in Attock district.
