A blast at a mosque in the northern Afghan city of Mazar-e-Sharif has caused dozens of casualties, officials said on Thursday.
"Preliminary reports confirm there are at least 25 casualties," Zabihullah Noorani, head of Balkh province's Taliban-run information and culture department.
Dr. Ghawsuddin Anwari, the head of the main hospital in northern Mazar-e-Sharif, where the explosion took place at the Sai Doken mosque, told The Associated Press that at least 10 people were killed and 40 injured.
The attack occurred as worshipers were kneeling in prayer during the Muslim holy month of Ramadan.
It comes just two days after several blasts hit educational facilities in in Kabul, killing at least six people, mostly children.
"IS" has claimed responsibility for the attack on its Telegram channel.
