Officials said a family in the apartment did not use their liquid petroleum gas tank properly. The tanks are often used in Chinese homes to supply gas for cooking.

Videos online showed at least one person being taken by first responders into an ambulance and the street covered in debris.

The explosion occurred at roughly 7 a.m. Harbin is the capital of China's northeastern Heilongjiang province.
