A bombing at a mosque in the Afghan capital of Kabul during evening prayers killed at least 21 people, including a prominent cleric, and wounded at least 33, eyewitnesses and police said.
There was no immediate claim of responsibility for the attack, the latest to strike the country in the year since the Taliban seized power. Several children were reported to be among the wounded.
The Islamic State group's local affiliate has stepped up attacks targeting the Taliban and civilians since the former insurgents' takeover last August as US and Nato troops were in the final stages of their withdrawal from the country. Last week, the IS claimed responsibility for killing a prominent Taliban cleric at his religious centre in Kabul.
Khalid Zadran, the spokesman for Kabul's police chief, gave the figures to The Associated Press for the bombing at the Sunni mosque.
According to the eyewitness, a resident of the city's Kher Khanna neighbourhood where the Siddiquiya Mosque was targeted, the explosion was carried out by a suicide bomber. The slain cleric was Mullah Amir Mohammad Kabuli, the eyewitness said, speaking on condition of anonymity because he was not authorised to talk to the media.
