Eight boys and their coach remain trapped in the caves, with rescue operations now on hold after the first entry depleted resources. "They have not been moved to Chiang Rai hospital yet", Tossathep told the Kyodo news agency.
Medics appeared to remove one person on a stretcher but hid the person's identity behind multiple white umbrellas.
The first of the boys trapped inside a cave in Thailand have been brought out by rescuers, reports say. Nine people remained trapped in the cave, including the team's coach, as of Monday morning.
Interior affairs minister Anupong Paojinda said Monday their health is good but declined to elaborate.
"The boys' strength, the plan - today we are ready like before. And we will do it faster because we are afraid of the rain".
Final Rescue Mission For Trapped Thai Boys' Football Team Is Underway
Operations to pump water out of the cave went on despite heavy rain showers on Sunday and Monday. President Donald Trump congratulated the Thai SEALs on Twitter.
The only way to bring them out is by navigating dark and tight passageways filled with muddy water and strong currents, as well as oxygen-depleted air.
Mild weather and falling water levels over the past few days created optimal conditions for an underwater evacuation, but that won't last if it rains again, Narongsak said.
Sky News correspondent Alex Rossi, who has been in Chiang Rai province this week, said: "The mood has lifted somewhat but there's still a long way to go".
The rescue of the first six was a stunning victory in an operation Narongsak had earlier dubbed "Mission Impossible", and led to cautious optimism that the others would also be saved.
Rescuers brought out the last five on stretchers, one by one over the course of Tuesday, and they were taken by helicopter to hospital. At the hospital, the team is being checked for airborne lung infections and bacterial infections that they could have developed after being in a damp cave environment for an extended period of time.

As of Monday morning, eight boys and their coach remained in the cave where they have been trapped by floods since June 23. 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.
The world has been watching, and an global team of divers and support crews were assembled to aid the rescue. On 5 July local time, he lost consciousness when distributing air tanks inside the caves and could not be revived.
The four boys emerged from Tham Luang Nang Non cave where they had been stranded for over two weeks after being rescued by foreign and Thai divers. Musk, head of Tesla and the Boring Company, tweeted that the tube would be "light enough to be carried by 2 divers, small enough to get through narrow gaps" and "extremely robust".
Thai Navy SEALS and dozens of volunteer rescue workers have worked around the clock funnelling food and oxygen into the cave and trying to train the soccer team and their coach to dive with heavy scuba gear on their backs. Officials first thought the rescue would take months but the rainy season has changed plans.
