The first images have emerged of 41 men trapped for a tenth day under a collapsed road in India.
It showed some dozen men in construction hats grouped around the blocked tunnel as they communicated with rescuers on the ground with walkie-talkies.
The video was taken by a snakelike medical endoscopy camera fed through a newly installed pipe used for sending food to the workers.
It was the first time in more than a week that the men received hot food, made up of rice and lentils, sent through the six-inch tube.
Until now, the workers have survived off dry food sent through an even narrower pipe, while oxygen continues to be supplied through a separate one.
Despite reports of some workers falling ill last week, authorities confirmed the group was safe, having also received water, medicine and access to light.

Rescue teams will need to clear 103m of rubble to reach the men – nearly double the distance as the original rescue attempt.
There is hope to get a “breakthrough in the next 30 to 40 hours” according to Mahmood Ahmed, the head of the National Highways and Infrastructure Development Corporation (NHIDCL) responsible for building the tunnel.
Its construction is part of a flagship federal government project connecting various Hindu pilgrimage sites.
The trapped men are low-wage workers, most from poor states in the north and east of India.
