This is Michael Safi carrying on our coverage of EgyptAir flight MS804, which we now know to have crashed in the Mediterranean Sea around 180 miles (290km) north of Alexandria.

Some officials suspect terrorism – albeit with little evidence so far. In the past few hours we’ve seen reports the aircraft sent warnings of smoke in the lavatories and electronics in the seconds before it disappeared from radar screens – the most promising clue so far as to what brought MS804 down.

Egyptian authorities are looking into those reports. We’ll bring you any updates here.
