A hospital director in northern Afghanistan says a bombing that targeted a campaign rally of President Ashraf Ghani killed 24 people. The president was at the scene but was unharmed in the blast and is safe.

Dr. Qasim Sangin at the Charakar hospital in northern Parwan province says another 31 people were wounded in the attack. He says there are women and children among those killed and wounded.

No one claimed responsibility for the attack, which comes as the country heads into presidential elections later this month despite relentless violence plaguing Afghanistan.

The Taliban have warned Afghans not to vote and said they would target polling stations and election campaigns.

More to come.
