The Thai official overseeing the effort to rescue members of a teen soccer team trapped in a flooded cave says a third rescue operation has begun Tuesday and aims to bring out the remaining four boys and their coach.

Chiang Rai Gov. Narongsak Osatanakorn says the rescue mission began at 10.08 a.m. and involves 19 divers. He said a medic and three SEALS in the cave, who’ve been looking after those trapped, will also come out.

Narongsak said, “We expect that if there is no unusual condition … the 4 boys, 1 coach, the doctor, and 3 SEALs who have been with the boys since first day will come out today.”

The eight boys rescued after being trapped for more than two weeks were described as generally healthy.
