Thai officials announced on Sunday (local time) that rescue efforts were underway for 12 boys and their soccer coach who have been trapped in a cave for the past two weeks.

One official was quoted by local media as having said that the rescue operation will likely take three to four days, depending on the weather.

Earlier, authorities instructed media and non-essential personnel to leave a camp site near the entrance to the cave, AFP reported.

Only diving teams, medics and security forces remain at the site, according to the BBC.

The unexpected order came a day after the rescue mission chief said conditions were perfect for the evacuation to begin, and as fears mount that coming rains could thwart the plan.

"Everyone who is not involved with the operations has to get out of the area immediately," police announced via loudspeaker at the site.

"From the situation assessment, we need to use the area to help victims."

They gave a deadline of 9:00 a.m. to clear out, setting off a frenzy of moving and packing.

Officials did not clarify whether the complex effort to dive the team out of the kilometers-long Tham Luang cave in northern Thailand had commenced.

At the start of the weekend the head of the mission Narongsak Osottanakorn said that the boys were not ready to make the trip, but later Saturday he suggested that there was a window to try.

"Now and in the next three or four days, the conditions are perfect (for evacuation) in terms of the water, the weather and the boys' health," Narongsak told reporters, according to AFP.

Sustained heavy rains could make the water rise to the shelf where the children are sitting, reducing the area to "less than 10 square meters", he added, citing estimates from cave divers and experts.

The death of a former Thai Navy Seal diver who ran out of oxygen in the cave on Friday underscores the danger of the journey even for adept professionals.

The "Wild Boars" team has been confined in the Tham Luang cave since June 23, when they entered after practice and were hemmed in by rising floodwaters.
