Five people, including two RAF personnel, have been killed in a helicopter crash in Afghanistan.
The Puma Mk2 helicopter crashed as it was landing at Nato's Resolute Support mission headquarters, Kabul. Nato has not released the nationalities of the other victims or the five left injured.
A Ministry of Defense spokesman has said the crash was "an accident and not the result of insurgent activity".
The families of the British victims have been informed, the MoD said.
They have asked for a period of grace before their names are released.
The accident comes after a convoy of UK military vehicles was attacked in Kabul, the Afghan capital, on Sunday morning. Seven people were injured and there were no UK casualties, the MoD said.
The MoD has said an improvised explosive device caused an explosion, while officials in Kabul said it was a suicide bombing. The Taliban said it carried out the attack in retaliation for air strikes in Kunduz which killed civilians and doctors.
The two RAF personnel killed in the helicopter crash were from 230 and 33 squadrons, both of which are based at RAF Benson, Oxfordshire, the MoD spokesman said.
He added: "The helicopter crashed while landing at the headquarters of Resolute Support: the Nato train, advise and assist mission in Afghanistan.
"The incident is currently under investigation but we can confirm that it was an accident and not the result of insurgent activity." (Foreign)
