On 19 February 1978, Egyptian special forces raided Larnaca International Airport near Larnaca, Cyprus, in an attempt to intervene in a hijacking. Earlier, two assassins had killed prominent Egyptian newspaper editor Yusuf Sibai and then rounded up as hostages several Arabs who were attending a convention in Nicosia. As Cypriot forces were trying to negotiate with the hostage-takers at the airport, Egyptian troops launched their own assault without authorization from the Cypriots. The unauthorized raid led to the Egyptians and the Cypriots exchanging gunfire, killing or injuring more than 20 of the Egyptian commandos. As a result, Egypt and Cyprus severed political ties for several years after the incident.
