“We are trying our best. We cannot tell the boy’s condition yet,” the rescuer said, identifying himself only as Sau.
According to media reports, rescuers have tried drilling and softening the surrounding soil to try to pull the pillar up to save Nam.
Authorities “are not sure about the current condition of the boy. He has stopped interacting with the outside though oxygen had always been pumped into the” hole, the Vietnamese Tuoi Tre newspaper reported.
On Monday, Prime Minister Pham Chinh asked federal-level rescuers to join efforts by local authorities to save the boy.
