Prime Minister Narendra Modi on Tuesday telephoned Sikkim Chief Minister Prem Singh Tamang to review the rescue operation following the NHPC Teesta Stage VI hydropower project tunnel collapse in Namchi district, assuring the state of every possible assistance from the Centre. At least seven workers have lost their lives in the tragedy, with rescue teams continuing efforts to reach those still trapped inside the under-construction tunnel at Samardung, Jholungey.

What the Prime Minister Said

According to the Sikkim government, Prime Minister Modi enquired in detail about conditions at the collapsed tunnel and reviewed the progress of ongoing rescue efforts. He expressed deep concern over the tragedy and conveyed his sympathies to the affected workers and their families.

Modi assured Chief Minister Tamang of the Centre's full backing for both rescue operations and relief measures. Tamang, in turn, thanked the Prime Minister for his prompt intervention, saying the assurance had provided 'strength and reassurance' to the state administration as teams worked under challenging conditions.

Rescue Operation on War Footing

Multiple agencies are engaged in the rescue mission, including the National Disaster Response Force (NDRF), State Disaster Response Force (SDRF), Sikkim State Disaster Management Authority (SSDMA), district administration, Sikkim Police, Fire and Emergency Services, and medical teams from Rangpo Primary Health Centre. Local volunteers have also joined the effort.

Specialised rescue teams from Pakyong and Siliguri have been deployed to bolster the operation. Chief Minister Tamang said he was closely monitoring the mission and had directed all concerned departments to expedite operations and maintain the highest safety standards.

Impact on Affected Families

Tamang expressed profound grief over the loss of lives and assured the families of deceased workers of the state government's full support. He praised the dedication, courage, and professionalism of rescue personnel engaged in what officials have described as a complex and demanding operation.

The Chief Minister also appealed to the public to remain calm, refrain from sharing unverified information, and keep the affected workers and their families in their prayers.

Background and What Comes Next

The NHPC Teesta Stage VI project is a major hydropower undertaking in Sikkim, a state that has faced recurring infrastructure challenges due to its mountainous terrain and seismic sensitivity. This comes amid heightened scrutiny of tunnel safety protocols at hydropower construction sites across the Himalayan region, following a series of incidents in recent years.

Officials confirmed that seven workers had died as of Tuesday, while efforts to recover remaining trapped workers were continuing. The Sikkim government reiterated its commitment to conducting the rescue safely and efficiently, and to extending all necessary assistance to affected families. The full scale of the tragedy is expected to become clearer as operations progress.

Point of View

And the loss of at least seven lives demands scrutiny of tunnel safety protocols at hydropower sites across the region. With several such projects underway in Uttarakhand, Himachal Pradesh, and Sikkim, this tragedy should not be treated as an isolated event. Accountability for site safety standards at NHPC-run projects must follow once the immediate rescue phase concludes.
