A central Beirut building home to offices, broadcaster Al Jazeera and the embassies of Norway and Azerbaijan was evacuated Thursday after alleged Israeli threats, AFP reports according to a Lebanese security source.

“The building administration received three phone calls claiming to be from Israel, repeating an order to evacuate the building,” the source told AFP, requesting anonymity and adding: “As the calls were via an app, it was not possible to determine their source or seriousness” so the building containing dozens of offices and firms “was evacuated”.
