A Fort Worth, Texas hotel was the scene of an explosion on Monday resulting in at least 21 injuries and a chaotic scene of destruction with windows, concrete, and a gaping hole in the sidewalk left in the aftermath.

The Fort Worth Police Department reported that they were working a major incident in the downtown portion of the city and advised people to avoid the area, though it was later revealed by the city's fire department that an explosion happened at the Sandman Hotel.

Fort Worth Fire Department Public Information Officer Craig Trojacek said 21 people were injured from the explosion, with one person in critical condition, four listed in serious condition and the rest with minor injuries. He added that 14 people were transported to area hospitals.

The fire department said the explosion was "likely caused" by a gas leak, but they were unable to officially confirm the cause. The department said construction was going on in the building at the time of the explosion.

Atmos Energy crews are on the scene and assisting with turning off gas in the surrounding area.

Fire crews are still searching for people inside the building, according to Trojacek.
