After a football practice on Saturday June 23, 12 young players and their “Wild Boars” team coach entered the 10km (6 mile) Tham Luang cave complex in Chiang Rai province, northern Thailand.
When they failed to return home, a huge search operation was launched, with rescuers facing a race against time to find them as heavy rain battered the region and flooded parts of the cave.
After 10 days, they have now been found weak but alive. Here is how the events unfolded.
25 June Search and rescue operation begins
Police say they are working with local authorities and divers in the search for 12 boys aged 11 to 16, as well as their coach.
They are believed to have entered the Tham Luang Nang Non cave in Chiang Rai province.
The young team, known as the Wild Boars, became trapped when a heavy rainstorm flooded a stream at the cave’s entrance.
Bicycles and football boots belonging to the boys are found near the entrance of the cave.
The search begins at about midnight after police receive a report of a missing child from a mother who says her son has not returned from football practice.
26 June Cave drained for divers to join search
Specialists pump out water to allow navy divers to operate in the cave complex.
Thailand’s interior minister Anupong Paojinda says divers can proceed only when enough water has been pumped out, to give breathing space between the water and the ceiling.
He says rescuers are working night and day.
“I want to confirm to the media that the SEAL team will be working non-stop because it’s already dark here too,” he says.
27 June Heavy rain hampers search efforts
Persistent heavy rain deters hopes to reach the boys and their coach as military teams struggle through water inside the cave.
Commander Buncha Duriyapan says: “Last night we worked non-stop in order to drain water out of the cave as much as possible.”
General Chalermchai Sittisart of the Thai army says hope has not been lost.
“We still have hope. All agencies are trying their best. We have a challenge from the water level which keeps rising.”
28 June British divers join rescue
Three cave diving experts from Britain fly to Chiang Rai province to help the search, five days after their disappearance.
Richard William Stanton, Robert Charles Harper and John Volanthen enter the cave in full kit before emerging an hour later.
Some of the rescue divers are forced to turn back after floodwater seeps into a second chamber of the caves, with heavy rain continuing to hamper the search.
30 June Thai police drop food packages for missing team
After six days missing, packages are dropped through a shaft in the mountainside in the hope of reaching the boys and their coach.
Twenty packages filled with water, food, medicine, torches and a note addressed to the missing team are dropped down a fissure in the cave.
Colonel Kraiboon Sotsong says: “If the children find this box we want them to float the box out of the cave.
“The note says: ‘If received, then reply and show on the map where you are. Everybody will quickly help.”
1 July Rescuers believe missing team has a chance of survival
Divers continue searching the murky waters as heavy rain causes flooding, preventing them getting through chambers to get deeper into the cave.
After the rain eases, divers from the Thai Navy SEAL unit are able to make progress through the waters filling passages of the underground maze.
Chiang Rai governor Narongsak Osottanakorn says: “The situation is better today than yesterday and the day before.
Rescuers say they believe the boys have a chance of survival, with possible access to fresh water inside the cave – either dripping though rocks or rushing in through the entrance.
2 July Boys found alive after 10 days
There are jubilant scenes as rescuers confirm they have found the boys and their coach alive, but “very weak”.
Governor Narongsak says they are safe but the rescue operation is not over, as they now need to get them out.
“Now the difficulty is getting them out because they are underground within this massive cave complex,” says Sky News’ Lisa Holland, who is at the scene.
“Things have been complicated because the underground complex is completely flooded due to heavy monsoon rain.”
The moment the boys were reached by a British rescuer was captured on video.
He can be heard reassuring the youngsters that “many people are coming”.
Torchlight shows the frail-looking boys sitting on a muddy bank inside the cave, with water between them and the rescue party.
The British rescuer, who has not yet been named, is thought to be either Richard William Stanton or John Volanthen.
