The incredible rescue has been deemed a miracle by many, but the operation wasn't without tragedy.
The plan, he said, is to bring out the four boys and their coach on Tuesday if the weather cooperates.
On the Twitter-like Sina Weibo site, the hashtag "Thai boys football team rescued" ranked 39th on Tuesday night in China.
But a person with knowledge of the rescue said just before the twelfth person was spotted, that in all, 11 of the 13 had been brought out.

The football team had spent the past week building their strength and learning to dive after they were discovered inside the cave by British divers last Monday. One diver, a retired Thai Navy SEAL named Saman Kunan, died in the rescue effort last week.
"The 12 Wild Boars and coach have emerged from the cave and they are safe", the Thai navy SEAL unit said on its official Facebook page.
Narongsak said he hopes the effort will be faster than yesterday, but added that today's operation will be the hardest because it will involve five people.
Loosely translated, it read: "Full face masks; two divers accompanying one boy; guided by a rope".

They were not the only members of football's fraternity to send their support to the Thai boys and their rescuers.
The 31cm-wide custom submarine would make the boys passive participants in the rescue and could potentially shorten the journey, which took divers a total of nine hours in the second successful rescue operation on Monday. He was taken by helicopter and ambulance to the same hospital in Chiang Rai where the first four boys rescued Sunday by a team of worldwide and Thai dive experts are being treated.
