On February 13, 1978, the Sydney Hilton Hotel was the site of one of the few terrorist incidents on Australian soil, when a bomb blast killed three people (two council workers and a policeman).
The Hilton Nicosia in Nicosia, Cyprus, was the scene of the assassination of Youssef Sebai, an Egyptian newspaper editor and friend of Egyptian President Anwar El Sadat, on February 19, 1978. The assassination and the hijacking of a Cyprus Airways DC-8 at Larnaca Airport led to the Egyptian raid on Larnaca International Airport by Egyptian forces. The intervention by the Egyptians led to the deterioration of relations between Cyprus and Egypt.
