The BBC has contacted the UK Foreign Office, the Greek authorities and the aviation company for comment.

A senior police official told The Times that the crash came just before the helicopter's scheduled landing time of 18:15 local time (16:15 GMT).

Sifnos' Deputy Mayor, Manolis Foundoulakis, arrived at the scene shortly after the incident and told local news site Newsit there was almost "nothing left" of the aircraft.

He said locals saw the helicopter crash within metres of their homes and had described a "bizarre engine noise coming from the aircraft" as it was about to land.

He said two of the victims were found in the wreckage, while the third was a short distance away.

Firefighters worked to tackle a blaze which broke out after the crash, and the flames had been extinguished by Monday evening.
