Videos and photos on social media and elsewhere appear to show people searching the destroyed mosque and moving a worshipper’s body from the gruesome scene to an ambulance.
Taliban chief spokesman Zabihullah Mujahid said the Shiite mosque was the target and that a “large number” of worshippers were killed and wounded. He said Taliban special forces had arrived to the scene and were investigating the incident.
The cause of the blast was not immediately clear. No group has yet claimed responsibility for it.
The Taliban leadership has been grappling with a growing threat from the local Islamic State affiliate, known as the Islamic State in Khorasan. IS militants have ramped up attacks to target their rivals, including two deadly bombings in Kabul.
IS has also targeted Afghanistan’s religious minorities in attacks.
