At least 14 people were injured, six of them with serious injuries, after an explosion hit a warehouse and an apartment building in southern Minneapolis.
According to first reports quoted by CNN, the incident happened on Wednesday, December 1 and so far the causes for the explosion are unknown. Six people are in critical condition in a local hospital.
John Fruetel, chief of firefighters in Minneapolis, told CNN that most of the victims had various burns throughout their bodies, and the diagnosis of the six people in critical condition has not been released due to their injuries.
The spokesman for the Emergency Medical Services of Hennepin County, Robert Ball, told The New York Times that many of those injured present "trauma consistent with a fall from a considerable distance," however, so far it is unknown if people jumped from the building or if the explosion threw them out.
Likewise, investigators are trying to determine if all of the building's residents could be evacuated during the fire that completely consumed the building on the early morning of Wednesday.
Firefighter teams tried to extinguish the fire; however, below-zero temperatures made the job harder for rescue teams, according to Fox News.
Rescue units and firefighters have not been able to carry out a complete search of the building, Ball explained, so it's feared that the number of people injured or perhaps killed might rise.
The explosion and resulting fire happened in Cedar-Riverside, in southern Minneapolis, in a densely-populated area, mostly by Somali-American residents, according to The New York Times.
