There were no immediate reports of unrest after the incident in Kabul.

Afghan Interior Minister Zarar Ahmed Moqbal and Kabul police chief Gen Amanullah Guzar were swiftly at the scene of the accident to oversee security measures.

May riots

Police in Kabul said the military truck was involved in an accident with a motorcyclist before crashing off the road into a house in the Saray Shomaly area on the outskirts of the capital.

The US-led coalition forces said that a tow truck had "flipped over into a 15ft embankment" after it hit a motorcycle that had "suddenly slowed down in front of the truck".

"Reports indicate there were injuries at the scene, to include the possible death of a child," a statement said.

It added that coalition forces deeply regretted any death or injury caused by the accident.

Last month, a similar traffic accident involving a US military truck in the Afghan capital caused the death of a number of people and sparked widespread rioting across Kabul.

Afghan MP Shukraia Barakzi visited the scene of Tuesday's crash and told the BBC that US forces should be held to account for traffic accidents.

"The way the Americans are driving is against traffic rules and regulations," she said. "If an Afghan kills someone in America in a road accident people don't try him in an Afghan court - instead they try him in an American court."

Official killed

Meanwhile Ghazni police chief Tarfseer Khan told the BBC the province's security director, Noar Ahmed Khan, had been killed on Monday night by the Taleban in Waghaz district.

The BBC's Bilal Sarwary in Kabul says Ghazni has seen a dramatic rise in violence in recent weeks, with attacks on Afghan troops, police and US-led coalition forces.

Hundreds have died, most of them alleged insurgents, as security has worsened in Afghanistan this year, particularly in the south and east.
