Two men have successfully climbed out of the one of the world's largest cave chambers, using only a safety rope.

Climbers Stefan Glowacz and Chris Sharma spent two weeks ascending more than 300m (984ft) of the Majlis al Jinn cave in Oman.

The challenge had never been attempted before, and was captured on film.
