Blast at election centre in Afghan capital, at least four dead

A suicide bomber blew himself up outside a voter registration centre in the Afghan capital Kabul on Sunday, killing at least four people and wounding more than 20, officials said.

The attack follows several weeks of relative quiet in Kabul and there was no immediate claim of responsibility.

Interior Ministry spokesman Najib Danesh said a bomber on foot approached the centre where officials had been issuing identity cards as part of a process of registering voters for parliamentary elections this year.

Ashmat Stanekzai, an adviser to the Kabul police chief, said at least four people were dead and more than 20 wounded but the final toll may increase.
