A suicide bombing ripped through a Shiite mosque in northern Afghanistan on Friday, killing at least seven worshippers, a government official said.
"A blast has taken place at a Shi'ite mosque," Baghlan province official Mawlawi Hashimi said.
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 Shiites, he said.
The 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.
Sunni Islamist militants consider Shiites to be heretics.
