In a letter of his own, the coach, Ekapol Chanthawong, apologized to the boys' parents for the ordeal.
After a short deluge of rain on Saturday night and with more bad weather forecast, Narongsak on Sunday said authorities had to act immediately. We will have to do the next mission as successfully as the one we did today'.
Now that the first of the boys have been taken to a nearby hospital, doctors there will begin evaluating the impact to their long-term health. "The rest of the kids are in the same spot", head of the rescue operation Narongsak Osottanakorn said.
"People don't understand how much gear these guys have", Zweig said of the rescuers.
The third boy emerged from the cave at about 19:40 local time, tightly followed by the fourth one. Several ambulances were seen coming to and from the cavesite.
Residents cheered at helicopters passed overhead and ambulances rumbled by in the streets - while young men rode around in flatbed trucks cheering, the Times reported. The other boys have not been identified yet.
Narongsak explained the group made a decision to move forward with the mission because heavy rains are expected in the area in the coming days, which could have further complicated the rescue.
According to a document released by the Thai authorities, two divers will accompany each of the teenagers.
Additionally, the continuance of the rescue operation is dependent on the weather holding out, with rain potentially causing delays.
"Now and in the next three or four days, the conditions are flawless (for evacuation) in terms of the water, the weather and the boys' health", Narongsak told reporters.
The group was found alive in a small cave chamber on Monday after nine days, mounting an worldwide rescue effort with experts weighing in from all over the world. The area outside the hospital was cordoned off with police patrolling the area, said a Reuters reporter at the scene.
To escape, the children must dive through dark, narrow passageways sometimes no more than 0.6m (two-feet) wide, that have challenged some of the world's leading cave divers.
The rescued boys were fitted with full-face masks for oxygen and had to travel more than a half-mile underwater in the struggle to reach safety along the 2.4-mile escape route, the governor said.
"We've been working continuously overnight", a Chiang Rai government source told AFP on Monday morning, requesting anonymity, and confirming that there had only been a pause of the actual extraction operations.
Last night, the Thai navy SEALS posted a message to their Facebook page which said: 'Have a good dream tonight. It remains unclear how numerous boys have actually left the cave. The plan was to have the boys swim out of the cave with the help of divers.
