Suicide bomb in Kabul Shia mosque kills dozens
A suicide bomber has killed at least 30 people inside a mosque in the Afghan capital Kabul, officials say.
An eyewitness told the BBC the scene at the Imam Zaman mosque, in the west of the city, "looks like a frontline".
The blast happened as worshippers were gathering for Friday prayers. The so-called Islamic State (IS) has targeted Shia mosques across Afghanistan.
In August, more than 20 people were killed in a bomb attack against worshippers in Kabul.
