Omani cavers descend into Yemen's 'Well of Hell'

Footage on social media gives a glimpse inside Yemen's newly-explored 'Well of Hell', a 30-meter wide sink hole and natural wonder in the country's Al-Mahra province in the southern part of the Arabian Peninsula.

The desert hole is 112-meters deep, says the Oman Cave Exploration Team (OCET), and has been largely undiscovered until its team of explorers ventured down with sophisticated equipment, finding different snakes, frogs, birds and pearls at the bottom. Light waterfalls also surround some parts of the cave.

For many years, the sink hole has been a topic of mystical tales for the province's residents.
