Australian embassy staff in Kabul have narrowly avoided being hit by a car bomb that exploded near their convoy as they travelled through the Afghan capital.
Foreign Minister Julie Bishop released a statement saying no Australians were injured, but local press reported a single casualty, a child selling vegetables from a cart.
"The Australian Government extends its sympathies to families and friends of people killed and injured in the attack," the statement said.
"The attack highlights the threat posed by terrorist and insurgent groups to the people of Afghanistan."
The explosion happened in a gated part of the capital that is popular with expats and also houses a military training centre.
Kabul has endured a spike in violence in recent weeks, including a bomb planted in an ambulance which killed more than 100 people.
