MAE SAI, Thailand (AP) — Electricians are extending a power line into a flooded cave in northern Thailand to help the search and rescue efforts for 12 boys and their soccer coach stranded three nights in the sprawling caverns and cut off by rising water.

Rescuers led by elite navy divers were forced to suspend their search Monday night due to flooding but were to resume Tuesday.

The boys, aged 11-15, and their coach were believed to have entered the cave in Chiang Rai province late Saturday afternoon.

Officials said pouring rain flooded parts of the cave with at least 5 meters (16 feet) of water but they believe the boys are alive.

Officials said the power line would provide lights and ventilation for the rescuers and could help pump out water.
