DIVERS FACE TOUGH CHALLENGE TO FREE TRAPPED BOYS

'Rescue is not a one-step process', says team leader

Wang Yingjie waited at the entrance to the cave, paying close attention to any sign that his fellow divers would emerge from the water. It would take more than six hours to dive from the entrance to their destination, far away in the depth and darkness.

He and his team are part of the rescue crew for a missing Thai youth soccer team found alive late on Monday after being trapped for 11 days. The 12 boys, ages 11 to 16, went missing with their coach on June 23.
