Islamic State has claimed responsibility for an explosion near a polling station in Quetta, Pakistan, according to the group's AMAQ news agency.
At least 24 people were killed and 35 injured in the blast in the western city of Quetta on Wednesday, which happened as Pakistanis vote in a knife-edge national election.
The group said the attack was carried out by a suicide bomber but did not provide further detail or evidence for its claim.
Earlier this month, a suicide bomber killed 149 people at an election rally in the town of Mastung, also in Baluchistan province.
The attack was claimed by Islamic State militants.
