The youngsters, aged between 11 and 16, and their 25-year-old coach went into the Tham Luang cave in northern Thailand after football practice. They were reported missing by a mother after her young son did not come home that night.

Relatives keep a vigil outside the cave where they will stay for nine days straight desperately awaiting news.

A miracle, finally: the 12 boys and their coach are found alive and safe about 400 metres further along from Pattaya Beach - which had become threatened by encroaching flood waters.
Crowds at the teeming rescue site cheer the good news and a nation breathes a sigh of relief.
But attention now turns to the difficult task of now getting the boys out safely.
The main priority is to get them food and first aid after nine days with little to eat in difficult conditions.
It could take days - or weeks - to get them out. Rescuers explore several options, including training them to use scuba equipment.
