Four more boys were rescued on Monday from a cave in Thailand where they had been trapped with their soccer team and coach for more than two weeks, according to multiple reports.

Eight of the 12 boys who had been trapped have now been taken out of the cave. Four of the boys remain, along with a coach from the team.

The first four boys were rescued on Sunday by a team of world-renowned cave divers, but the mission was put on hold for 10 hours as rescuers refilled the oxygen tanks that had been depleted.

All eight of the boys taken from the cave are receiving treatment in a hospital.

The rescue efforts have been suspended for the day and will continue Tuesday.

The rescue operation is extremely risky, and one ex-Thai Navy SEAL died delivering oxygen tanks to prepare for the first rescue.

Tesla and SpaceX CEO Elon Musk sent a group of engineers to Thailand to assist with the rescue efforts, which involve over 90 people.
