At least four labourers were killed and 14 injured after a portion of a cold storage collapsed in Chandapur village in Prayagraj, officials said, as rescuers sifted through the debris to search for survivors.
The collapse also triggered an ammonia gas leak from the facility and efforts were being made to contain it, the officials said.
District Magistrate Manish Kumar Verma told PTI, "14 labourers were injured in the incident and are receiving treatment at SRN Hospital. Four labourers have died."
Teams from the district administration, police, State Disaster Response Force, and the fire brigade are engaged in relief and rescue operations.
Prime Minister Narendra Modi and Uttar Pradesh Chief Minister Yogi Adityanath expressed grief over the incident and announced financial assistance of ₹2 lakh for the kin of the deceased and ₹50,000 for the injured.
