The death toll from a bombing at a Sufi shrine in southern Pakistan on Saturday rose to 43, with dozens of others injured, home minister for southwestern Balochistan province said.

"At least 43 people have been killed and dozens others wounded," Sarfraz Bugti told a press conference in the southwestern port town of Gwadar, without providing a precise figure for those injured.

A senior police official and a security official confirmed the death toll.
