A US review of satellite imagery has not produced any signs of an explosion aboard the EgyptAir flight so far, officials from multiple US agencies have told Reuters.
Officials, speaking on condition on anonymity, said the conclusion was a result of a preliminary examination of imagery.
They cautioned against media reports that suggested the US believed a bomb was responsible, and added they had not ruled out any possible causes for the crash, including mechanical failure, terrorism or a deliberate act by the pilot or crew.
Work has begun on analysing data from the two black boxes from the fated EgyptAir flight that crashed into the sea in May.
French air accident investigators confirm the signal detected earlier is from a flight recorder.
The head of Egypt's forensics authority said it is 'too early' to know what caused the EgyptAir plane to crash into the Mediterranean sea.
