Gurkhas go on the attack against litter

Gurkhas in Kent are on the attack. Their target - piles of litter which have blighted the cliffs at Folkestone.

The soldiers, based at Shorncliff Barracks, are used to negotiating difficult terrain and hazardous environments. The operation was not a military manoeuvre, but part of a community event marking The Queen's 90th birthday. Derek Johnson reports.
