Afghan officials say a suicide bomber has attacked a voter registration center in the capital, killing at least four people.

Public Health Ministry spokesman Wahid Majro says another 15 people were wounded in Sunday's attack. Kabul police spokesman Akmal Ahmadzai confirmed the location of the attack.

No one immediately claimed responsibility. The Taliban and a local Islamic State affiliate both view Afghanistan's government and democratic elections as illegitimate.

Afghanistan will hold parliamentary elections in October.
