Iran Denies Shooting Down Passenger Jet Steve Herman WHITE HOUSE - Iran is denying allegations that one of its missiles shot down a Ukrainian jetliner outside Tehran and is urging the U.S. and Canada to provide any information about the crash that killed all 176 people on board. Iranian Civil Aviation Organization chief Ali Abedzadeh said Friday at a Tehran news conference that "what we can say with certainty is that no missile hit the plane." Abedzadeh said if the U.S. and Canada are sure about its suggestions the plane was mistakenly hit by a missile, "they should come and show their findings to the world," in accordance with world standards. Iranian investigative team leader Hassan Rezaeifar said recovering information from the plane's black box fight recorders could take more than a month. He also said Iran may ask international experts for help if it is not able to extract the data.
