An explosion at a five-star hotel in London late Friday left at least 14 people injured and forced hundreds of guests to evacuate.
The Associated Press noted that authorities said Saturday that the blast is believed to have started in the basement of the Hyatt Regency London - The Churchill and was set off by a gas leak.
BBC News reported that the London Fire Brigade said the explosion happened just before midnight and caused part of the building to collapse. Five cars parked on a nearby street were also damaged.
Several people were transported to a nearby hospital and treated for injuries. The hotel said those being treated are Hyatt employees. No guests were injured.
"Hyatt's top priority is the safety and wellbeing of our guests and associates, and we are currently working to provide guests with accommodations while we evaluate whether the hotel suffered any significant damage," the company said in a statement.
The surrounding area, littered with broken glass and rubble, was closed off to traffic. The incident remains under investigation.
