The U.N. civil aviation body said Friday it was not responsible for issuing warnings about potential dangers such as military conflicts, saying that duty fell to individual nations.

The role of the International Civil Aviation Authority has come under scrutiny after a Malaysian airliner was shot down by a missile Thursday over eastern Ukraine, killing all 298 people on board.

Montreal-based ICAO rejected suggestions it should have issued a warning about the potential dangers of flying over the area.
