Three Afghans have been killed in an attack on the Bagram air base in Afghanistan, officials have said.
Five missiles were fired into the US base, causing a fire which destroyed a Chinook helicopter, a spokesman for the International Security Assistance Force (Isaf) said.
The overnight attack also wounded a number of Isaf personnel.
It comes a day after the US military handed a nearby controversial prison over to the Afghan authorities.
The jail houses more than 3,000 Taliban fighters and terrorism suspects and has been at the centre of a number of prisoner abuse allegations.
The Taliban have claimed responsibility for the Bagram assault.
