Bangkok (VNA) – Thai Prime Minister Prayut Chan-o-cha on June 29 visited a cave in the northern province of Chieng Rai where 12 boys and their soccer coach are believed to be trapped for nearly a week.

From June 29 morning, boxes containing food and water, map, mobile phone were released into the water. It is expected to be picked up as the water flows toward the cave's mouth.

Police reportedly began dropping plastic boxes with essentials into a hole on the ground, hoping they will somehow get to the boys.

International rescue teams, including one sent by the US Indo-Pacific Command, are assisting the Thai army, navy and police in the search, which has been hampered by heavy rain.

The Thai authorities said that they believed the trapped could have reached a large, dry cavern, and officials were considering drilling through the mountaintop to reach them.
