An ambulance is seen at Chiang Rai Prachanukroh hospital, where four of 12 Thai schoolboys who were rescued from the flooded cave are being treated, in the northern province of Chiang Rai, Thailand, July 9, 2018.
The focus is now on the eight remaining members of the football team and their coach, whom divers hope to bring out after rescuing four boys on Sunday.
The boys and their coach, all from the "Wild Boars" soccer team, became trapped by rainy season floodwater on June 23rd when they had set out to explore the vast cave complex after soccer practice. On Monday, a second rescue operation by the same team of divers took only nine hours to bring out the next four.
The first four boys, from the group of 13, including the coach, were rescued on Sunday.
"The operation went much better than expected", mission head Narongsak Osottanakorn said on Sunday.
However he declined to specify when the second day's mission would be completed or how many members of the Mu Pa team members would be evacuated on Monday. Four boys and their football coach are still trapped inside the cave.
The network says Narongsak attributed the speed gains to "the increased experience with the terrain of the divers, the 100-plus people from different countries who installed the base line and the other support equipment".
"The water level is not worrisome ... yesterday's rain did not affect water levels inside the cave". They wore full-faced masks "while hanging on to the bodies of rescue divers", Channel News Asia reported.
She added that the four boys rescued on Sunday were hungry and asked for a local dish. A massive worldwide search operation was launched and it took 10 days to locate the boys, who had taken shelter on a dry slope deep in the complex.
Six hours after operations restarted on Monday morning, rescue workers carried the first stretcher from the mouth of the cave to a waiting ambulance, which then sped away with its lights flashing.
"The water level is low". "I can help him with his homework", he said.
Narongsak estimated that the precarious journey out could take 10-12 hours for each boy and that extracting everyone could take days.
The Thai Navy Seal Facebook page has confirmed reports that eight of the boys have now been rescued.
Former Thai navy SEAL Saman Kunan passed out making the dive on Friday and died.
