The search for a missing Thai youth boys soccer team has entered its seventh day, raising fears for the boys and their coach. The team apparently hiked into the Tham Luang Nan Non caves June

23 and become trapped by rising flood waters. The Wild Boars team consists of 12 boys, aged 11 to 16, and their 25 year old coach. The team had explored the caves, a popular hiking spot for

tourists and locals, in the past. They began their hike about 1 p.m. local time that Saturday. Hours later, a park ranger in the Chiang Rai province noticed their bikes still chained up at

the entrance of the caves long after the park had closed and alerted authorities, according to CNN. Due to heavy rains, floodwaters had risen inside the cave, possibly cutting off the

have swum three miles into the cave, while drones have swept the six mile stretch of cave looking for heat signatures. With each passing day, fears have increased about the boys'

survival. "Physically, it's not a hard cave, it's just very long and it has big passages, small passages," Vernon Unsworth, British cave expert and Chiang Rai resident

told CNN, "It's not difficult but if the children have gone in too far then the floodwaters from the far end will be coming through. With the rain, it's not making it any

easier." The mud, floodwater, and narrow passageways throughout the cave have proven difficult for even trained divers to navigate, _The New York Times_ reported on Friday. The Tham

Luang caves are a vast network of passageways and possible dry chambers, with signs warning visitors to stay away during the rainy season. Thai Prime Minister, Prayut Chan-o-cha, visited the

rescue site on Friday and told families, who have been camped outside the caves since the disappearance, to have faith, CBS News reported on Friday.
