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.
An attacker on a motorbike blew himself up near the entrance, an Isaf spokeswoman told Reuters news agency.
Kabul security has been tightened as supporters of an anti-Taliban warlord mark 11 years since his assassination.
