A new report from the crashed EgyptAir flight 804 has emerged. According to the report, flight data suggested that smoke alarms were set off minutes before it crashed in the Mediterranean Sea early on Thursday.

Alazeera reports that the Aviation Herald website, which tracks incidents and news in the aviation industry, said it received information that smoke alarms went off in the toilets of the Airbus A320 before the crash.

It also reported smoke alerts in the proximity to the electronics and equipment bay of the aircraft.

However, the authenticity of the data has not been officially confirmed.

The signals were reportedly sent via the ACARS, or Aircraft Communications Addressing and Reporting System, which transmits short condition updates to ground stations by radio or via satellite.

The Aviation Herald said it received information from three independent channels, that ACARS (Aircraft Communications Addressing and Reporting System) messages with the following content were received from the aircraft:

The EgyptAir Airbus 320, carrying 66 people from Paris to Cairo, vanished early on Thursday shortly after leaving Greek airspace.

The plane had been cruising normally in clear skies on the nighttime flight to Egypt's capital when it suddenly lurched left, then right, spun all the way around and plummeted 38,000 feet into the sea, never issuing a distress signal.

Egyptian authorities were investigating the reports of smoke alerts.

"We are looking into this report," an Egyptian civil aviation ministry official told the AFP news agency. "At this point I can't deny or confirm it."
