Watch: First video of trapped tunnel workers in India’s Uttarakhand

Officials have released first footage of the 41 workers who have been trapped inside a tunnel in India's Uttarakhand state for nine days.

The footage was shot on an endoscopic camera which was inserted inside the tunnel on Monday.

The men have been stuck since 12 November after a landslide caused a portion of the tunnel to collapse in the state's Uttarkashi district.
