Two major incidents occurred in 1972. The Fatah subgroup Black September Organization hijacked Sabena Flight 572 en route to Vienna and forced it to land at the Ben Gurion International Airport in Lod, Israel. The PFLP and the Japanese Red Army carried out a shooting rampage at the same airport, killing twenty-four civilians. Israel later claimed that the assassination of PFLP spokesman Ghassan Kanafani was a response to the PFLP's involvement in masterminding the latter attack. Two days later, various PLO factions retaliated by bombing a bus station, killing eleven civilians.
