Chamoli tunnel rescue: Teams search for three missing after flooding

Imagine workers were building a big underground tunnel in the mountains.

Suddenly, lots of water and mud rushed into the tunnel and trapped some of the workers inside.

There were 22 people working in the tunnel when the accident happened.

Rescue teams have been able to save 12 of them.

Sadly, they found the bodies of 7 workers who did not survive.

Three workers are still missing, and rescuers are still looking for them.

The tunnel is now partly filled with dark, muddy water, which makes it very hard to search.

Rescuers used a small makeshift boat to float through the flooded part of the tunnel.

They are also searching by hand in areas where the water and mud are thick.

Many rescue teams are working together and taking turns to keep searching.
