The first video of the Thai boys rescued from a flooded cave after 17 days was released on Wednesday, showing them smiling and waving from their hospital beds, looking thin but fine after an ordeal that has gripped the world.

The last group of the 12-member "Wild Boars" soccer team and their coach was brought out of the Tham Luang cave, near the border with Myanmar, on Tuesday night, safely ending a dangerous rescue and evoking international relief and joy.

Rescue mission chief Narongsak Osottanakorn told a news conference the boys were just being children when they got lost and no one was to blame.
