New video footage of the Thai football team trapped deep inside a cave displays the youth laughing and expressing wellness, subsequent to the 11 days declared missing by family and rescue crews.

A video posted on the Facebook page of the Thai Navy SEALs on Wednesday depicts the pale, thin boys, many of them wrapped in foil warming blankets, introducing themselves and saying they are “in good health”.

At the end of the one-minute video, one of the footballers demonstrates humor, noting he was skipped in the round of introductions.

Two more videos posted on the Royal Thai Navy Facebook page show divers treating minor wounds and some of the boys smiling while others sleep underneath their blankets.

A mother of one of the boys teared up, AFP news agency reported. “He is thinner,” she said.

The 12 boys, aged 11 to 16, and their 25-year-old coach were found on Monday evening, nine days after becoming trapped inside the Tham Luang cave complex in northern Thailand’s Chiang Rai province after floods caused by heavy rains blocked its entrance.

Reports say extracting the football team from the flooded cave may take several weeks.
