8 September 2012 Last updated at 12:04 BST

A suicide bomber has killed at least six people near the headquarters of the Nato-led international coalition (Isaf) in Kabul.

A number of children are among the dead. There were no reports of casualties among Isaf troops.

The BBC's Jonathan Beale was about a mile from the scene in Kabul and said that he heard an explosion followed by sirens.
