An explosion at a mosque used as a voter centre in the eastern Afghan province of Khost has killed at least 17 people and wounded 34, local officials said, in the latest attack on preparations for long-delayed parliamentary elections.
Basir Bina, spokesman for the provincial police, said people were gathered after afternoon prayers in the mosque on Sunday, which was also being used as a voter registration centre for parliamentary elections due in October.
He said the blast appeared to have been caused by explosives left in the mosque rather than by a suicide bomber, reports Reuters.
Habib Shah Ansari, head of the health department in Khost, a mountainous region on the border with Pakistan, said 17 were confirmed dead from the blast with 34 injured.
There was no immediate claim of responsibility for the explosion, which adds to a series of attacks on voter centres since the registration process began in April. The Taliban, which has warned people against taking part in the election process, issued a statement denying any involvement.
Medical aid group Medecins Sans Frontieres said it had donated emergency supplies to the Khost provincial hospital where many of the wounded were taken.
