Practice Relating to Rule 7. The Principle of Distinction between Civilian Objects and Military Objectives
Following investigations by the Secretary-General of the International Civil Aviation Organization (ICAO) into the shooting down of two civil aircraft by the Cuban air force on 24 February 1996, a debate took place on 26 July 1996 in the UN Security Council, during which Poland asserted that the principle that States must refrain from resorting to the use of weapons against civil aircraft in flight was well established in customary international law and codified in Article 3 bis
of the 1944 Chicago Convention. According to Poland, an attack against a civilian aircraft in flight violates elementary considerations of humanity.
