"ICAO" is presumably International Civil Aviation Organization, a UN agency. Wikipedia says:
Most air accident investigations are carried out by an agency of a country that is associated in some way with the accident. For example, the Air Accidents Investigation Branch conducts accident investigations on behalf of the British Government. ICAO has conducted three investigations involving air disasters, of which two were passenger airliners shot down while in international flight over hostile territory.
1. Libyan Arab Airlines Flight 114 which was shot down on 21 February 1973 by Israeli F-4 jets over the Sinai Peninsula during a period of tension that led to the Arab-Israeli Yom Kippur War killing 108 people.
2. Korean Air Lines Flight 007, which was shot down on 1 September 1983 by a Soviet Su-15 interceptor near Moneron Island just west of Sakhalin Island during a period of heightened Cold War tension killing all 269 people on board including U.S. Congressman Larry McDonald.[26]
3. UTA Flight 772, which was destroyed by a bomb on 19 September 1989 above the Sahara Desert in Niger, en route from N'Djamena, Chad, to Paris, France. The explosion caused the aircraft to break up, killing all 156 passengers and 15 crew members, including the wife of U.S. Ambassador Robert L. Pugh. Investigators determined that a bomb placed in the cargo hold by Chadian rebels backed by Libya was responsible for the explosion. A French court convicted in absentia six Libyans of planning and implementing the attack.[27]
