Water pumps failed shortly after the last boy was freed in the Thailand cave rescue operation on Tuesday night (NZ time).
Seventeen days after they were trapped underground, the rescue operation successfully retrieved all 12 boys from the Wild Boars football team and their coach from the flooded cave in Chiang Rai.

Just hours after the last boy was freed, water pumps in the cave failed while divers and rescue workers were in chamber three - over 1.5km inside the cave.
Three divers involved in the operation told The Guardian they heard screaming from inside the cave, after the main pump failed causing water levels to increase rapidly.
Shortly after the pumps failed, everyone was out of Tham Luang cave.
The Wild Boars team became stuck in the cave in Chiang Rai on June 23 when heavy rain caused flooding and closed off their only route out.
British divers discovered them nine days later, beginning a rapid, high-stakes rescue mission before the weather deteriorated further.
The boys began to be pulled out on Sunday night, with four boys being rescued on the first day of the mission and a further four the following night.
Thai Navy SEALs completed the rescue operation by pulling out the final four boys and their coach late on Tuesday night.
