Officials in Afghanistan say a powerful explosion at a mosque in the northern city of Kunduz has killed at least 46 people. The Islamic State militant group has claimed responsibility.
The blast occurred on Friday afternoon. The provincial government says more than 140 people were injured.
Reports suggest more than 300 people were present at the mosque to attend prayer service at the time. It is frequented by Shia Muslims, a minority in the country.
In a statement issued on Friday, the Islamic State group said a militant blew himself up inside the mosque.
The latest attack is said to be the most severe since the Taliban formed an interim government in September.
