TEHRAN (Press Shia) – A suicide bomber blew himself up outside a voter registration center in the Afghan capital Kabul on Sunday, killing at least 25 people and wounding dozens as they waited to receive identity cards, officials said.

There was no immediate claim of responsibility for the attack.

The Taliban’s main spokesman issued a statement on Twitter denying involvement, Reuters reported.

Interior Ministry spokesman Najib Danesh said a bomber on foot approached the center where officials had been issuing identity cards as part of a process of registering voters for the election scheduled for October.

A spokesman for the ministry of public health said at least 25 people were confirmed dead and scores wounded. The explosion destroyed cars and shattered windows in nearby buildings, leaving rubble strewn across the street.

“There were women, children. Everyone had come to get their identity cards,” said Bashir Ahmad who had been nearby when the attack took place, after weeks of relative calm in the capital.

The blast took place in Dasht-e Barchi, an area of western Kabul inhabited by many members of the mainly Shiite Hazara minority.

Voter registration centers have been set up across Afghanistan ahead of long-delayed parliamentary and district council elections due to be held in October.
