In June/July 2018, a junior association football team became trapped for fifteen days in Tham Luang Nang Non, a cave system in Chiang Rai province, northern Thailand, but were ultimately rescued. Twelve members of the team, aged 11 to 16, and their 25-year-old assistant coach entered the cave on 23 June after a practice session. Shortly after they entered, heavy rainfall began and partially flooded the cave system, blocking their way out and trapping them deep within.
