Escalation: Death Toll Rises to 15 in Sikkim Collapse

On Monday afternoon, a methane gas explosion triggered the collapse of a tunnel at a state-run hydropower project in the Himalayan state of Sikkim, India. As of July 21, multiple workers were confirmed dead and others remained trapped.

Fatality counts varied across early reports: Muslim Network TV, Ednews.net, and an Azerbaijani outlet said at least nine were killed; Yahoo News New Zealand and The Jerusalem Post reported 10; The Hindu reported 12. The number of trapped workers was put at about 15 by The Jerusalem Post and Dawn, while other outlets said "several".

Rescue crews struggled to enter the tunnel because of lingering fumes and toxic gas. "Survival chances were slim," state disaster management official Rajiv Roka said, as teams battled the hazardous air inside, according to The Jerusalem Post.

Dawn reported an official estimate that roughly 25 to 27 workers were in the area when the blast happened. The tunnel is in remote, mountainous terrain, which complicates access and slows rescue work.

The Hindu said Prime Minister Narendra Modi offered support as state authorities coordinated the response. Rescue operations were ongoing on July 21, with teams racing to reach the trapped workers despite the dangerous gas buildup.
