Rescue police will on Friday drop dozens of survival boxes containing food, maps and mobile phones into chimneys near the Tham Luang cave, hoping they will reach the 13 persons trapped there a week ago.
The boxes also contain messages which ask that the finder to phone the rescue team and tell them their location and the extent of their water and medical supplies.
The boxes will be dropped into waterways and open channels at Doi Pa Mee cliff near the cave with the hope that they will float to within reach of the missing group. The boxes also contained blinker, pens for marking, mobile phones of three providers, flashlights, candles and lighter.
A group of 12 young football players and their assistant coach went missing in the cave which is in Tham Luang-Khun Nam Nang Non Forest Park last Saturday, triggering a massive search. They are believed to be trapped in the cave due to the flash floods that have hit the area.
Rescue teams are desperately seeking alternative entrances into the cave to reach the boys. However, as the one-week marker of their cave entry approaches, the operation has not yet been able to locate them.
Authorities are hoping that the team sought shelter now in an area inside the cave nicknamed Pattaya Beach, with rescuers led by a Thai Navy SEAL team focused on reaching that site as soon as possible.
