A big explosion happened in a tunnel where workers were building a hydroelectric project in Sikkim, India.
Nine workers died, and more than 15 are still trapped.
The explosion might have been caused by a gas leak.
Rescuers are trying to save the trapped workers, but it's very hard because the air inside the tunnel is not good to breathe.
The government and the company involved are working to find out what exactly happened.
A blast in a hydroelectric tunnel in Sikkim, India, killed nine workers and trapped more than 15 others.
The blast was likely caused by a natural gas leak, but the exact cause is still under investigation.
