Tham Luang: Chiang Rai province Governor Narongsak Osotthanakorn has said it is too dangerous for the Thai soccer team to be extracted from the cave for now, while also confirming fresh oxygen will be pumped in.

In comments made overnight at the Tham Luang cave complex, Governor Narongsak said conditions were good in the first three chambers of the cave and it was still possible to walk this section.

But he warned "the problem is beyond the T-junction, where the water level is quite high. At that point, the passage bends and the water level is very high".

"According to the plan, if we let them dive out, the most dangerous point is extremely narrow, the boys will have to dive by themselves, the water is quite deep and long at that point and the [Thai Navy] SEALs can't be next to them."
