(FOX NEWS) -- The dozen boys of a youth soccer team and their football coach have been found alive in a cave after they went missing over a week ago, according to a Thai official.

Chiang Rai Gov. Narongsak Osatanakorn said that the group are safe after a massive search operation took place in the Tham Luang Nang Non caves.

The boys, aged 11 to 16, and their 25-year-old coach entered the sprawling cave after a soccer game on June 23, and had not come out. Despite rain and rising floodwaters, authorities nevertheless expressed hope that the group had found a dry place within the cave to wait, and that they would remain alive until rescuers could find and reach them.
