A blast killed several civilians at a mosque in Kabul where people were holding prayers for the mother of the Taliban's spokesperson, officials in the movement said on Sunday, and gunfire was later reported on the outskirts of the city, Reuters reports.
There was no immediate claim of responsibility for Sunday's attack, apparently the most serious in the Afghan capital since the withdrawal of U.S. forces in August.
Several other civilians were hurt in the explosion on a main road near the entrance of the Eidgah mosque, officials said.
Taliban commanders were seen giving blood at a hospital treating the wounded. Media access was tightly controlled.
The attack underlined the mounting challenges facing the Taliban as they grapple to adapt to government and prevent a complete collapse of Afghanistan's war-battered economy, with millions threatened by famine as winter approaches.
The local affiliate of Islamic State, which has fought the Taliban for years, has already claimed to have carried out attacks on Taliban fighters, although officials from the new government have dismissed the threat from the group.
Hours after Sunday's blast, local media reported heavy exchanges of gunfire in Karezimir, an area immediately to the north of the city. Residents contacted confirmed they had heard explosions and gunfire. Reuters was not immediately able to determine who was involved.
Taliban spokesperson Zabihullah Mujahid confirmed the explosion had taken place. He did not comment on reports from other officials in the movement that the mosque had been holding prayers for his mother who had died recently.
