A 15-tonne army truck ran off the road during a Gurkha training exercise in the Western Isles.

The vehicle ended up in a ditch at the side of the A857 near Borve, Lewis, after trying to avoid a passing HGV.

Nobody is believed to have been injured in the crash on Thursday afternoon, which left the road blocked.

Troops from the Queen's Own Gurkha Logistic Regiment are visiting the Hebrides this month to learn how to drive in difficult terrain.

A British Army spokesman said: "It is a driving exercise focused on maximising time behind the wheel allowing the soldiers to develop and practise their skills in challenging and unfamiliar terrain, which is key to shaping the ongoing force development of the unit."

About 100 troops are participating in the exercise, which involves 30 vehicles being taken from Aldershot in Hampshire to Stornoway on Lewis.

They include Land Rovers, six and 15-tonne MAN support vehicles, and a Mastiff armoured patrol vehicle.

The isles of Lewis and Harris are being used as staging areas for the 12-day operation.

The Gurkhas are Nepalese soldiers whose compatriots have served in the British armed forces for more than 200 years.
