Officials in Afghanistan say a bomb blast inside a mosque that was being used as a voter registration center has killed at least 14 people and wounded more than 30.

Afghanistan plans to hold elections in October, the first since 2014.

Also Sunday, an Afghan official said seven Indian citizens and their Afghan driver were kidnapped in the northern Baghlan province.
