Dead bodies of 10 workers have been recovered after a 36-hour long rescue operation in Jammu and Kashmir's Ramban district, officials said. The workers were buried under debris following a massive landslide after an under-construction tunnel cave-in at Khoni Nallah along the Srinagar- Jammu highway. Experts say the failure of the construction company to follow protection norms may have led to the tragedy. Police have filed an FIR for negligence.
