Ludhiana: An ammonia gas tanker leak along a canal on the Doraha Bypass road killed 5 people and put 100 others in the hospital as they complained of breathing problems. “Those affected after inhaling the gas have been admitted to various hospitals in Ludhiana. Barring 2-3 persons, all were stated to be out of danger by the doctors,” Ludhiana Police commissioner Pramod Ban said. Locals came out of their houses even as the gas from the leaking tanker spread in and around Doraha, police said, adding that residents of the surrounding areas had to be evacuated after the incident.
