A suicide attack at a voter registration centre in the Afghan capital Kabul has killed at least 34 people, officials say.
More than 60 others were injured in the blast which hit a crowd waiting at the entrance to the building.
The Islamic State group (IS) has claimed via its Amaq news agency that it carried out the attack.
Voter registration began this month for legislative elections which are due to take place in October.
The Amaq report said that a suicide bomber wearing an explosive belt targeted the centre, which is in the Dashte Barchi area of western Kabul.
Images from the scene show blood-stained documents and photographs on the floor.
Abandoned shoes and broken glass litter the area and nearby vehicles are riddled with holes.
Eyewitness Bashir Ahmad said many of the victims were women with children who were there to get their identity cards and register for the elections.
There have already been at least four attacks on such centres since voter registration got under way a week ago.
