Rescuers are searching for at least two people trapped under the rubble of a collapsed building in the Belgian city of Liege.
The five-storey apartment block gave way at around seven o’clock in the morning local time, five hours after an explosion that authorities believe was caused by a gas leak.
Twenty people were hospitalised and two of them are said to be in a critical condition.
The initial explosion damaged buildings up to 100 metres away. Firefighters were in the process of trying to get two people out from under the debris when the building collapsed.
