Boeing jet crashes in Iran with no survivors, security sources see technical cause

A Ukrainian airliner fell to earth in a fireball shortly after take-off from Tehran on Wednesday, killing all 176 people on board in a crash that sparked an international scramble to establish the cause. The Ukraine International Airlines Boeing 737-800, en route to Kiev and carrying mostly Iranians and Iranian-Canadians, crashed hours after Iran fired missiles at bases housing US forces in Iraq, leading some to speculate that the plane may have been hit. But five security sources who asked not to be named said the initial assessment of Western intelligence agencies was that the plane had suffered a technical malfunction and had not been brought down by a missile. There was evidence one of the jet’s engines had overheated, the Canadian source said. “We are in contact with our airline customers and stand by them in this difficult time. We are ready to assist in any way needed,” the manufacturer said in a statement earlier on Wednesday. In Paris on Wednesday, the maker of the plane’s engines, French-U.S. firm CFM - co-owned by General Electric and France’s Safran - said speculation regarding the cause was premature. Smoldering parts and debris, including shoes and clothes, were strewn across a field southwest of the Iranian capital, where rescue workers in face masks laid out scores of body bags. Among the victims were 82 Iranians, 63 Canadians, and 11 Ukrainians, Ukrainian authorities said. Canadian Prime Minister Justin Trudeau said at a news conference on Wednesday afternoon that 138 of the passengers were connecting to a flight to Canada. The Tehran-Toronto via Kiev route was a popular one for Canadians of Iranian descent visiting Iran, in the absence of direct flights, and carried many students and academics heading home from the holidays.<br/>
