Three men were killed and another was left in critical condition after inhaling toxic gases while attempting to rescue a bull from inside a 40-feet-deep well in a village in Madhya Pradesh's Maihar district.
Local residents are breathing toxic gases across this industrial city that has surpassed the degree of pollution of the national capital for the second consecutive day and topped the list of hazardous cities in the country, as the pollution index chart prepared by the Central Pollution Control Board reflects.
