Two workers at a Nepali power plant have been rescued from a tunnel nine days after floods devastated the region, with hopes rising for the others trapped inside as rescue crews report hearing even more voices.

The unidentified men were pulled from a small hole at the Trishul 3A hydropower plant in quick succession on Friday, officials said. 

Local television news channels showed images of the worker covered in mud and being carried from the site on a rescuer´s shoulder. A medical team was checking on him at the site, Basnet said.

The rescue came nine days after the August 26 floods, likely caused by a glacier collapse, that devastated towns and valleys in Nepal.
