MONTREAL (Reuters) - The United Nations aviation agency is looking to bolster support for families of victims of air disasters as it members continue to debate strategies for preventing planes from being shot down over conflict zones or disappearing.

A recommendation that is winding its way through the Montreal-based agency would urge states to come up with concrete plans to help families of plane-crash victims, Nancy Graham, director of the U.N.'s International Civil Aviation Organization's (ICAO) Air Navigation Bureau said on Wednesday.
