“A blast has taken place at a Shia mosque,” Baghlan province official Mawlawi Hashimi said. The mosque was located in Pol-e-Khomri of the province, according to Tolo News.

Seven people were killed during prayer and 15 injured in the attack in the city of Pul e Khumri in Baghlan, he said. All of the casualties were Shias, he said.

Islamic State militant group claimed responsibility for the attack in a post on the Telegram messaging app.

Afghanistan’s Taliban-run administration has faced an insurgency by IS militants, who have claimed a series of deadly attacks on civilians, foreigners and Taliban security forces in recent months.
