Thai officials say they hoped to bring the rest of the group trapped in the the Tham Luang cave out today. 

Four of the boys and their football coach are still deep in the Tham Luang cave, BBC reported. 

The first eight boys rescued from a cave in northern Thailand are in good mental and physical health, according to a health official.

The boys, who were brought out of the caves over the past two days, have undergone X-rays and blood tests. Two have been treated for lung inflammation.

They will remain under observation in hospital for at least seven days.

The group became trapped on 23 June after heavy rains caused flooding. They were found last week by divers.
