Three soldiers from Belgium had to be airlifted to hospital over the weekend after falling ill and sustaining injuries while on exercise in South Uist.
Stornoway Coastguard confirmed it received a call for assistance at 9.30am on Sunday morning.
A spokesperson for the coastguard said that three servicemen were airlifted by helicopter from South Uist to the airfield in Stornoway. An ambulance then transported the soldiers to Western Isles Hospital.
It is understood one of the soldiers dislocated his ankle, while the others were suffering from exhaustion.
They were on exercise on the east coast of South Uist, an area totally inaccessible to any mode of transport other than a helicopter.
A large detachment of Belgian soldiers is currently based in the islands, undertaking training at Hebrides Range and completing land exercises across North Uist, Benbecula and South Uist.
