The Lod Airport massacre was a terrorist attack that occurred on 30 May 1972. Three members of the Japanese Red Army recruited by the Popular Front for the Liberation of Palestine (PFLP), attacked Lod Airport (now Ben Gurion International Airport) near Tel Aviv, killing 26 people and injuring 80 others. Two of the attackers were killed, while a third, Kōzō Okamoto, was captured after being wounded.
The dead comprised 17 Christian pilgrims from Puerto Rico, a Canadian citizen, and eight Israelis, including Professor Aharon Katzir, an internationally renowned protein biophysicist. Katzir was head of the Israeli National Academy of Sciences, a popular scientific radio show host, and a candidate in the upcoming Israeli presidential election.
