An Afghan man walks outside a voter registration centre, which was attacked by a suicide bomber in Kabul.
Dozens of Afghan citizens died Sunday simply because they wanted to vote. He said 119 people were wounded, among them 17 children and 52 women, and "the tolls could still rise".
Voter registration in Afghanistan has been low - groups in opposition to the government have threatened violence at such centers, and a string of fraudulent and delayed elections have caused voter apathy.
Sheets of paper and passport-sized photos lay scattered amid shattered glass and pools of blood on the street near badly damaged cars - grim evidence of the force of the blast. A suicide bomber detonated an explosive device when he was stopped for checking by the local police. "God damn the attackers!"
The Islamic State has claimed responsibility for the attack.
Afghanistan will hold parliamentary elections in October and voter registration started a week ago.
Afghanistan's global partners have insisted the elections should be held this year before a presidential vote due in 2019.
No one immediately claimed responsibility for the killing, but Khogyani blamed the Islamic State group, which has been active in Chaparhar and repeatedly claimed attacks in the district.
The targeted election ID centre is situated in Dasht-e-Barchi area, a neighbourhood known for being dominated by Shia Hazara community.
Afghan police officers inspect the scene of the attack. The Sunni group has frequently targeted Afghanistan's Shi'ite minority, whom it views as "apostates".
BBC research this year found the Afghan government had full control over just 30 percent of the country, with the rest under significant threat from the Taliban and - to a lesser extent - IS.
