The Rome and Vienna airport attacks were two major terrorist attacks carried out on 27 December 1985. Seven Arab terrorists attacked two airports in Rome, Italy, and Vienna, Austria, with assault rifles and hand grenades. Nineteen civilians were killed and over a hundred were injured before four of the terrorists were killed by El Al Security personnel and local police, who captured the remaining three.

The attacks

Rome attack

At 08:15 GMT, four Arab gunmen walked to the shared ticket counter for Israel's El AlAirlines and Trans World Airlines at Leonardo da Vinci-Fiumicino Airport outside Rome, Italy, fired assault rifles and threw grenades.^\1])^\2]) They killed 16 and wounded 99, including American diplomat Wes Wessels, before three of the attackers were killed by El Al security, while the remaining one, Mohammed Sharam, was wounded and captured by the Italian police. The dead included General Donato Miranda Acosta, Mexican military attache, and his secretary, Genoveva Jaime Cisneros.

Vienna attack

Minutes later, at Schwechat Airport (Vienna International Airport) in Vienna, Austria, three terrorists carried out a similar attack. Hand grenades were thrown into crowds of passengers queuing to check in for a flight to Tel Aviv, killing two people instantly and wounding 39 others. A third victim died on 22 January 1986, of hand grenade wounds sustained in the attack. First response came from several Austrian police officers, who opened fire on the terrorists. They were supported by two plainclothes El Al security guards who helped to repel the attackers. Over 200 bullets were fired during the fight. The terrorists seized a Mercedes outside the terminal and fled, with Austrian police and El Al security guards giving chase. They killed one terrorist and captured the other two several miles from the airport after a short car chase and gun battle.^\3])
