The Jordanian king was set to address the world's financial and political elite in a speech at 1845 IST, but the address was cancelled, WEF planners said.
Saudi Arabia's Prince Turki Al Faisal Al Saud, the half-brother to King Abdullah, also left the posh ski resort, cancelling a today morning appearance alongside ministers from Canada and Germany.
The elderly King Abdullah died earlier today and was replaced by another half-brother Salman as the absolute ruler of the world's top oil exporter and the spiritual home of Islam. He is to be buried later today.
