Nine people have been confirmed dead following an explosion at a steel plant in China’s northern Inner Mongolia Autonomous Region, according to state media reports on Tuesday. The incident occurred over the weekend at the Baogang United Steel plant, where a water and steam tank with a capacity of 650 cubic meters reportedly exploded. At least 84 people were hospitalized after the blast, and one person remains missing as rescue teams continue search operations.

Videos circulating on social media showed the plant’s collapsed roof, debris, and thick plumes of smoke rising into the sky. Firefighting vehicles were deployed to the site, and footage captured a large object being hurled into the air during the explosion. Residents living several kilometers away said the blast shook their homes and shattered windows.

The report noted that China has experienced several major industrial accidents in the past, including a fireworks factory explosion in Hunan Province last June that killed nine people and a 2015 chemical warehouse blast in Tianjin that claimed more than 170 lives.
