Thailand cave struggle: 4 boys rescued so far

New Delhi : Four out 12 boys have been rescued from a cave in Thailand and are in "perfect" health. The boys had to travel approximately 4 kilometers with the help of oxygen cylinders to make an exit. About 0.6 miles (1 kilometer) of the journey was underwater, where everyone had to wear full face masks.

According to reports, the boys did not know swimming and they were given swimming lessons before rescue operations. Experienced cave divers have noted how difficult the dive in Thang Luam Cave is. In addition to having no experience diving, the boys have mostly been without food and medicine for two weeks in tight quarters where oxygen is limited.

On Friday, it was reported that the oxygen level inside the cave had dropped from 21 percent to 15 percent, leading to complications in rescue efforts. A Thai Navy SEAL commander told reporters he believed there was "a limited amount of time" left to rescue the soccer team.

Other boys and the coach are still inside the cave where air is being provided with the helo of cylinders.
