Tunnel Explosion at Indian Hydropower Project Kills 10, Leaves 17 Missing

A suspected gas explosion triggered a collapse inside an under-construction tunnel at a hydropower project in India's northeastern Himalayan state of Sikkim, near the Chinese border, killing at least 10 workers and leaving 17 missing. The disaster underscores the dangers of the rapid infrastructure buildout across India's fragile mountain terrain. Rescue crews continued searching the debris as questions mounted over safety standards at large-scale construction sites.
