A CNN reporter, Veronica Rocha, quoted American cave rescue expert Anmar Mirza as issuing the warning.
“Cave rescue expert Anmar Mirza says diving out of the cave is the most dangerous option. He says the safest option is to shelter in the place until the water level goes down,” Rocha said in her Twitter message.
“The option to bring them out by diving is the quickest but it’s also the most dangerous," Mirza, national coordinator of the US Cave Rescue Commission, also told the BBC.
"Cave diving is a very technical skill and it's extremely dangerous, especially for an untrained diver," Mirza also told AFP.
"So they may end up being better off trying to supply them in cave until they can be gotten out by other means."
