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.
The Ukrainian International Airlines Boeing 737-800, flying to Kyiv and carrying mostly Iranians and Iranian-Canadians, crashed shortly after taking off from Tehran's Imam Khomeini airport, killing all 176 people on board.
