Afghan police say at least 25 people have been killed in twin suicide blasts at a Shi’ite mosque in southeastern Afghanistan.

Raz Mohammad Mandozai, the police chief of Paktia Province, said two suicide bombers detonated their explosives inside the Khawaja Hassan mosque in the provincial capital of Gardez on August 3.

Mandozai said the suicide bombers, who he said were disguised in burqas, first killed two security guards at the entrance of the mosque before firing on worshippers and detonating their explosives.

Mandozai said at least 40 people were wounded in the attack and were rushed to nearby hospitals.

Sardar Wali Tabasun, the police spokesman for Paktia Province, said the attack occurred after Friday Prayers.

Officials warned that the death toll could rise.
