First visuals: Uttarkashi tunnel collapse caught on camera

An unverified video of Uttarkashi tunnel collapse purportedly captured by one of the trapped workers on the day of the collapse is circulating on social media.

The footage shows debris falling, obstructing the tunnel.

One of the workers urging his team mates to move towards a safer area can also be heard. 

41 men trapped in a collapsed tunnel for 17 days were rescued on November 28.
