A suicide bomb attack on a mosque in the Afghan city of Kunduz has killed at least 50 people, officials say, in the deadliest assault since US forces left.
Images on social media showed bodies and debris inside the mosque, used by the minority Shia Muslim community.
More than 100 people were injured in the blast in the northern city.
No group has said it was behind the attack, but Sunni Muslim extremists, including a local Islamic State group, have targeted the Shia community.
They consider Shia Muslims to be heretics.
IS-K, the Afghan regional affiliate of the Islamic State group that is violently opposed to the governing Taliban, has carried out several bombings recently, largely in the east of the country.
Zalmai Alokzai, a local businessman who rushed to a hospital to check whether doctors needed blood donations, described seeing chaotic scenes.
“Ambulances were going back to the incident scene to carry the dead,” he told AFP news agency.
