FOUR more boys have been brought out of a flooded cave in northern Thailand as the ongoing rescue operation concludes for the second day, Thai officials said.

An aide to Thai navy Seals, Sitthichai Klangpattana, did not comment on the boys’ health or say how well the operation has gone at the Tham Luang Nang Non caves in Chiang Rai.

Eight of the 12 boys have now been brought out of the treacherous cave system by divers, including four who were removed on Sunday on the first day of the operation.

The boys and their 25-year-old coach have been trapped for more than two weeks after heavy rains flooded the sprawling cave network, comprising caverns connected by tight passages. Elite British divers have been assisting in the painstaking rescue operation.
