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 said.
Kabul security has been tightened as supporters of an anti-Taliban warlord mark 11 years since his assassination.
Ahmad Shah Massoud — a hero of the 1980s war against Soviet occupiers, and later of opposition to the Taliban — was killed by al-Qaeda suicide bombers on September 9 2001.
Following the explosion, the Isaf HQ, home to some 2 500 personnel, was placed “on lockdown”, the Isaf spokeswoman said.
Child street hawkers are believed to have been caught in the blast and witnesses said small bodies could be seen being carried to ambulances.
