An explosion has ripped through a crowd outside the entrance of a mosque in central Kabul on Sunday.

This has left a number of civilians dead, a Taliban spokesman said.

The blast targeted the gates of the Eidgah Mosque, where a funeral service for Taliban spokesman Zabihullah Muhajid's mother was being held.

Reports on social media described a large detonation and emergency services rushing to the scene.

There was no immediate claim of responsibility for the attack.
