Since the terrorist attacks of Sept. 11, 2001, and the tightening of security in and around airports around the world, there have not been many airport shootings. But they do happen from time to time. Some are committed by self-styled terrorists, and some are the result of other criminal behavior.
The incidents include:
July 4, 2002: Hesham Mohamed Hadayet, 41, an Egyptian who came to the United States a decade earlier, approached the El Al ticket counter at Los Angeles International Airport, pulled two guns and opened fire on dozens of people, killing two and wounding four others. An unarmed El Al security guard knocked the gunman to the floor. A second security officer, who was armed, ultimately shot and killed the gunman.
