The rescue operation at the SLBC tunnel in Telangana is facing increasing complexity, according to Minister Uttam Kumar Reddy. The operation to save trapped workers in the tunnel has entered its fifth day, with officials describing it as the most complex and extremely dangerous. The National Disaster Response Force (NDRF) has made progress, inching closer to the eight workers still trapped inside. Various technologies, including drones, sonars, and robots, are being used in the rescue efforts as time runs out. However, challenges such as slush and water seepage continue to hinder the operation.
