military planners in thailand are weighing their options for how to get a youth soccer team and their coach out of a flooded cave. new video shows the boys with blankets telling their families they're in good health after a weekend and a half under ground. navy s.e.a.l.s are staying with the group practicing swimming and showing them how to use oxygen masks. authorities are considering bringing the boys out one at a time with two divers assigned to each boy. now for more on this dramatic rescue effort, anna coren joins me from northern thailand. great to see you, my friend. the conditions there look remote, muddy, very difficult just for staging this rescue, not to mention spelunking through muddy water to reach these children. i understand they're trying to string up telephone lines so they can talk to their parents? >> yeah, that's right.
