A campaign to reduce the amount of litter in Scotland's waters has been stepped up after images of a stag with rope tangled in its antlers were released.

Scottish Natural Heritage (SNH) has highlighted the dangers of marine rubbish to wildlife on land by publishing the photos, which were taken on the Rumnational nature reserve.

The organisation revealed two deer had recently died on the island after they became tangled together with rope in their antlers.

Lesley Watt, reserve manager on Rum for SNH, said: "Marine litter is a huge international problem.

"But small actions can make a big difference and everyone has a part to play."
