The three men were rescued from the Trishuli 3A tunnel nine days after floods, likely caused by a glacier collapse, devastated towns and swept away villages in Nepal on Aug. 26.

Axar.az reports, citing ABC News, that Nepalese lawmaker Shri Ram Neupane posted about the second rescue on his Facebook page shortly after army spokesperson Brig. Gen. Raja Ram Basnet confirmed the first trapped worker’s rescue. Officials identified the two men as a mechanical foreman and a mechanical supervisor.

Local television news channels showed images of the first rescued worker covered in mud and being carried from the site on a rescuer’s shoulder. Both men were under medical observation, the officials said.

Officials present at the rescue site said rescuers believe some people may still be alive inside the tunnel.

Nepal’s Communication Minister Bikram Timilsina said officials remain hopeful that more workers will be rescued.

It should be noted that 1,204 people have so far been confirmed dead in the floods that hit Nepal on August 26, while around 4,500 people remain missing.
