A cave in Iceland has been badly damaged by too many tourists

One of Iceland's most beautiful natural attractions has been left in ruins after years of uncontrolled tourism. The Leidarendi Cave - near Reykjavik - has seen many of its stalactites and stalagmites destroyed - and much of the walls have been covered in graffiti. Conservationists say local tourist companies are to blame. The BBC's Tim Allman reports.
