Four Thai cave-boys freed, rescue ops continue to save remaining nine

Around 50 foreign elite divers and 40 Thai Navy SEALS begin ops to extract a group of 13 boys from the Tham Luang cave complex; bring out the weakest first.

Four boys among a group of 13 trapped in a flooded Thai cave for more than a fortnight were rescued on Sunday after surviving a treacherous escape, raising hopes elite divers would also save the others soon.
