A deadly explosion in the provincial capital of Kunduz in northern Afghanistan during Friday prayers in a Shia Muslim mosque killed at least 50 people and injured 150 others.

Iran PressAsia: A suicide bomb attack on worshippers at a Shiite mosque in the Afghan city of Kunduz killed at least 50 people Friday, in the bloodiest assault since the Taliban grab power.

Other reports indicated that 100 people had been killed, and more than 200 were injured.

The blast took place in the Khanabad Dandar area in the Khanabad district of the province while dozens of people were attending Friday prayer.

Dost Mohammad Obaida, the deputy police chief for Kunduz province, said that the “majority of them have been killed,” in reference to the victims. He said the attack may have been carried out by a suicide bomber who had mingled among the worshipers inside the mosque.

Witness accounts described a powerful explosion with many casualties. Mullah Rohani, a Taliban official in Kunduz, confirmed the death toll as "at least 43 people killed and said more than 140 were injured as well."

 Taliban spokesman Zabihullah Mujahid confirmed that the mosque was targeted, tweeting: "This afternoon, an explosion took place in a mosque of our Shiite compatriots in the Khan Abad district of Bandar, the capital of Kunduz province, as a result of which a number of our compatriots were martyred and wounded."

Shiite Muslims have long been a target of violence by extremists in predominately Sunni Afghanistan. The Taliban, which regained control of the country after two decades out of power, have specifically targeted the minority group in the past.

The attack comes as the Taliban contend with a growing threat from ISIS, who have stepped up their attacks in recent weeks.

Several civilians were killed or wounded in a bomb blast at a mosque in Kabul last week.
