Egyptian President Abdel-Fattah al-Sisi said on Sunday that no assumption is certain why the Egyptair plane crashed over Middleterranean the last week.
"All assumptions are possible," Sisi said in a televised speech during an inauguration ceremony of a petrochemical project in Damietta governorate.
"Reaching the reasons behind the plane crash takes long time... we will announce the results once we finish investigating," he said.
On Thursday, EgyptAir said that the MS804, an Airbus A320, disappeared from radar screens en route from Paris to Cairo at 2:45 a.m. Cairo local time (0045 GMT) on Thursday.
Also on Thursday, Egypt's Civil Aviation Minister Sherif Fathy said a terrorist attack was more likely than a technical failure that caused the crash.
The flight had 66 people aboard, including 30 Egyptians, 15 French, two Iraqis and nine others each from Algeria, Belgium, Portugal, Britain, Canada, Chad, Kuwait, Saudi Arabia and Sudan.
The Egyptian investigation committee said Saturday that it's "too early" to make judgments over the reason behind the recent EgyptAir plane crash.
