DUBAI, UNITED ARAB EMIRATES/KYIV ¨C Ukraine outlined four potential scenarios on Thursday to explain the deadly crash of one of its airliners in Iran, including a missile strike and terrorism, as Iranian investigators said the plane was on fire before it fell to the ground.
Kiev said its investigators wanted to search the site of Wednesday¡¯s crash southwest of Tehran for possible debris of a Russian-made missile used by Iran¡¯s military. An initial report by Iran¡¯s civil aviation organization said the plane had experienced an unspecified technical problem.
