It comes after a rescuer died overnight

Billionaire Elon Musk is sending a team of engineers to help in the Thai cave rescue.

The 12 boys and their football coach who've been trapped in a flooded cave in Thailand for around two weeks but it's hoped they could be rescued 'today or tomorrow'.

The Tesla and SpaceX boss says his team has special digging equipment and he's happy to help in any way he can.

Overnight a Thai rescuer died after falling unconscious during the rescue operation.

It's reported the 38 year old former Navy Seal was putting oxygen tanks along a potential exit route - but died from a lack of oxygen.

Thai authorities are racing to pump out water from the flooded cave where the group have been trapped since 23 June.
