The Ministry of Defence said it was investigating the circumstances of a UK helicopter crash that killed five service personnel in Afghanistan, but could not confirm the nationality of the troops involved.
An MoD spokesman said: "We can confirm that a UK helicopter crashed in southern Afghanistan today.
"The incident is under investigation and it would be inappropriate to comment further until families have been notified."
