Rescue teams battled to save a one-year-old girl that had fallen into a 50ft-deep well while playing in Thailand.

Police, firefighters, and disaster response officers were called to a cassava field in the border province of Tak after the toddler Tasa Mo-ei plunged down the shaft on February 6 afternoon.

Her parents Atay, 20, and Necho, 26, were hired to work in the fields and had brought their daughter along. They left the child unattended under the shade of a tree and went to plow at the plantation, only to find her missing when they returned.

Frantic Atay called out the child's name several times and was shocked to hear her voice from inside the deep hole, prompting her to call for help.

Rescue teams arrived and lowered a camera to check on Tasa Mo-ei's condition, finding her still alive and responsive.

They filled the narrow space with oxygen from tanks and commenced with the mission, widening the well's hole first using excavators, and later by hand.

The responders said they were operating under low visibility and were as the ground might collapse.

The rescue is ongoing as of 10 a.m. local time on February 7.
