Security has been stepped up in the Afghan capital Kabul following a fatal car crash believed to have involved two US embassy vehicles.
Four Afghans were killed in the accident, according to the city’s criminal investigations chief.
The occupants of an SUV, said to belong to the US embassy, reportedly fled the scene.
Police fired into the air to disperse a crowd of angry Afghans who shouted “death to America”, hurled stones and set fire to vehicles.
A deadly traffic accident caused by a US military convoy four years ago sparked an anti-American riot in the capital which left at least 14 people dead and dozens more injured.
Several NGO buildings were ransacked and torched, forcing the evacuation of hundreds of foreigners.
This time, however, it seems Afghan authorities are not taking any chances.
