Workers confirmed dead after the tunnel collapse.

Some reports indicate that 15 workers were initially trapped after the collapse, while other sources only mention 'several others trapped' without specifying a number. A rescue operation is underway.

The collapse was likely triggered by a blast, according to a source familiar with the incident. The exact cause is still under investigation.

The tunnel, which was under construction at the time of the incident, is located in Sikkim, a state in northeast India. Authorities have launched a rescue operation to reach those still trapped.
