Twelve boys and an assistant coach from a soccer team in Thailand are trapped in a flooding cave, leading to an 18-day rescue operation.

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.

June 23 is the 174th day of the year in the Gregorian calendar; 191 days remain until the end of the year.
