Desperate rescue underway for boys in Thailand cave

Twelve boys and their soccer coach have been missing in a flooded cave in Northern Thailand for almost three days - but officials believe they are still alive. The boys, aged 13 to 16, are believed to have entered the Tham Luang cave complex on Saturday afternoon. Divers have been unable to reach a large chamber deep inside the cave where the students might be, but have so far only found signs of the boys. Our correspondent in Thailand, Richard Ehrlich, tells us there is still hope for the group. [tags[ Thailand
