An explosion at a high-rise building in the US injured 23 people and temporarily trapped a window cleaning crew on a hanging scaffold.
Goy-one people were rushed to the hospital after the explosion in Baltimore, which caused the roof to partially collapse.
The city’s fire department tweeted that at least nine of the victims were in critical condition, while another was in serious condition.
The trapped workers were rescued through a window and firefighters continued to search the building.
The firefighters union tweeted that evidence points to an explosion on the 16th floor of the central building, where the offices of the Baltimore Gas and Electric Company are located.
The fire department said the cause of the blast remains under investigation, but public services spokeswoman Stephanie Anne Weaver said work on the building’s “boiler and air handling system” likely caused it.
“The window washing scaffold was compromised due to the incident and a window washing team was brought to safety by the fire department,” Ms. Weaver said in a statement.
The building was practically empty from the holidays and the coronavirus pandemic.
