Wahida Shahkar, a spokesman for the provincial governor, said the blast was caused by an improvised explosive device attached to a security vehicle on Tuesday afternoon, when the president began addressing an election campaign rally in the city of Charikar, the capital of Parwan Province.
Shahkar added that the explosion hit the entrance to the venue, killing at least 24 and injuring over 30 people.
“Women and children are among them and most of the victims seem to be the civilians. Ambulances are still operating, and the number of casualties may rise,” said Abdul Qasim Sangin, the head of the provincial hospital.
Reports said President Ghani was not hurt in the blast and was taken to safety.
