A huge bomb attack at a mosque in Kabul during evening prayers has killed at least 10 people, including a prominent cleric, and wounded at least 27 others.
There was no immediate claim of responsibility for the attack on Wednesday, the latest to strike Afghanistan in the year since the Taliban seized power.
Several children were reported to be among the wounded, amid fears that the casualty numbers could rise further.
Last week, IS claimed responsibility for killing a prominent Taliban cleric at his religious centre in Kabul.
The slain cleric was Mullah Amir Mohammad Kabuli, the witness said, speaking on condition of anonymity because he was not authorised to talk to the media.
He added that more than 30 other people were wounded. The Italian emergency hospital in Kabul said at least 27 wounded civilians, including five children, were brought there from the site of the bomb blast.
Khalid Zadran, the Taliban-appointed spokesman for the Kabul police chief, confirmed an explosion inside a mosque in northern Kabul but would not provide a casualty toll or a breakdown of the dead and wounded.
A US-led invasion toppled the previous Taliban government, which had hosted al-Qaida leader Osama bin Laden in Afghanistan, following the September 11 terrorist attacks in the United States.
Since regaining power, the former insurgents have faced a crippling economic crisis as the international community, which does not recognise the Taliban government, froze funding to the country.
Separately, the Taliban confirmed on Wednesday that they had captured and killed Mehdi Mujahid in western Herat province as he was trying to cross the border into Iran.
Mujahid was a former Taliban commander in the district of Balkhab in northern Sar-e-Pul province, and the only member of the minority Shiite Hazara community among the Taliban ranks.
Mujahid had turned against the Taliban over the past year, after opposing decisions made by Taliban leaders in Kabul.
