FlightRadar24 offers a ‘Full Flight History for EK17’ on various dates, although, 10JUN is not now included. I have checked out the routings flown of EK17 flights for various dates and they overfly Iran and then directly over the border to Turkey and do not over fly Iraq and Syria.
However, what was marked on the map also was a broken red line showing the theoretical direct routing between Dubai and Manchester and this possibly has been confused for the actual routing flown.
