On September 6, 1970, members of the Popular Front for the Liberation of Palestine (PFLP) hijacked three jets (Swissair, TWA and Pan Am ) with more than 400 passengers on flights to New York. A fourth plane, an El Al flight, was also targeted, but Israeli security agents foiled the hijacking in mid-air and killed one of the two terrorists when they tried to storm the cockpit. On the 9th, a British BOAC jet was also hijacked by the PFLP. This was the Security Council's statement in response.
