MONTREAL -- An expert says the recent plane crash in Iran highlights glaring gaps in flight safety rules.

Michael Bociurkiw, who was an observer in Ukraine's investigation into the 2014 Malaysia Airlines flight that was shot down, says some countries may be reluctant to close their airspace due to economic and political turmoil that could result, qualifying it as an “extreme” measure.

Aerospace consultant Ross Aimer believes that authorities are not fulfilling their role in protecting passengers and has called for a more active role to be played by the International Civil Aviation Organization (ICAO), a United Nations agency based in Montreal.

The agency says it only publishes warnings in cases of major military conflicts or air traffic control disputes.

States and governments are ultimately responsible for flight-risk notifications.

Last week, an Iranian missile shot down Ukrainian International Airlines Flight 752, killing 176 people on board, including 57 Canadians, hours after the Iranian military launched missiles against Iraqi military bases.
