Summary
At least 10 workers died after an under-construction tunnel at NHPC’s Teesta-VI hydropower project in Sikkim collapsed around midday Monday.
A sudden burst of methane gas from surrounding rocks triggered an explosion, NHPC said in a stock exchange filing, causing the cave-in.
The blast trapped 25 workers and officials inside the tunnel in Namchi district, and more people may still be buried.
The accident hit NHPC’s 500-megawatt project in India’s fragile Himalayan northeast, where earlier reports said rescue crews were contending with toxic gases.
