Traces of explosives have been found on victims of the EgyptAir flight MS804 plane crash over the Mediterranean in May, investigators have said. Following the announcement on Thursday, Egypt's civil aviation ministry released a statement saying that a criminal investigation would now begin into the crash of the Airbus A320. Flight MS804 from Paris to Cairo plunged into the sea on 19 May killing all 66 people on board. The Airbus A320 was carrying 40 Egyptians, 15 French, two Iraqis, two Canadians and one passenger each from Algeria, Belgium, Britain, Chad, Portugal, Saudi Arabia and Sudan. The cause of the crash has remained unclear but flight data suggested that rather than exploding in mid-air, the plane had flown into the sea. Egyptian investigators have confirmed the aircraft made a 90-degree left turn followed by a 360-degree turn to the right before hitting the sea.
