A landslide has caused a tunnel collapse in the Indian state of Sikkim, leaving at least seven people dead and several others missing, officials reported on Tuesday. The incident occurred at a construction site in the mountainous region, where a section of the tunnel gave way following heavy rain and earth movement. Rescue teams have been deployed to the area, working through debris to locate those who remain trapped. Local authorities have not yet confirmed the total number of workers inside at the time of the collapse, but fear the toll may rise. Sikkim, located in the Himalayas, often experiences landslides during the monsoon season, which can trigger infrastructure damage and casualties. The state government has launched an investigation into the cause of the collapse while prioritizing rescue efforts. Medical teams are on standby to treat any survivors. Family members of the missing workers have gathered near the site, waiting for updates. Officials have urged the public to remain calm as operations continue. This incident underscores the challenges of construction in hilly terrains, where unstable soil and weather conditions pose constant risks. The rescue operation is expected to last for several more hours as teams dig through the rubble. Updates will follow as more information becomes available.
