14 people were injured at a top London hotel after an explosion in the basement caused part of the building to collapse.
The Churchill Hyatt Regency hotel in Portman Square, central London, was evacuated following the suspected gas explosion at around 11.40pm on Friday and a number of people were being treated by paramedics.
London Ambulance Service said five of the injured were taken to hospital, including two with leg wounds, while nine others were checked over at the scene and given the all-clear.
Fire officers and gas engineers are ensuring the scene is safe so guests can be allowed back into the hotel.
London Fire Brigade said the explosion happened at about 23:40 GMT in the basement of the hotel, causing part of the building to collapse.
Around 80 firefighters were on the scene, including appliances with specialist equipment to deal with collapsed buildings. The full extent of the damage was not immediately clear and all people were accounted for, a spokesman for London Fire Brigade said.
Police officers were also on scene and a Metropolitan police spokesman said: “At about 11.40pm we were called to a suspected gas explosion at Portman Square. Officers are in attendance alongside the fire brigade and ambulance service. A small number of injured parties are being treated . The London fire brigade later tweeted there had been extensive damage caused to the basement.”
A fire brigade spokesman said 500 people had to be evacuated from the hotel.
The five-star hotel, in the Marylebone area, features 434 guest rooms.
Structural engineers have been called to assess the damage in the basement area.
