Divers are preparing to resume a high-risk rescue operation to free the last five members of a group who became trapped in a vast cave system in northern Thailand last month.

The health of the four boys and their football coach is said to be good as they ready to be guided through the narrow flooded passages of the complex.

Eight boys have been brought out of the caves over the past two days.

The operation inside the Tham Luang caves has attracted global attention.

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

How are the rescued boys?

The eight boys have not been seen in public, but have been pronounced to be in reasonable health.

The four who came out on Monday were stretchered from the caves and taken to a hospital in the nearby city of Chiang Rai.

The first group of four boys, who were rescued on Sunday, are being kept in quarantine in hospital and have yet to be reunited with their parents.

The Thai authorities say the rescued boys are able to eat rice porridge, although their request for a favourite pork dish has been turned down until their digestive systems recover from 10 days without food.
