Libyan authorities, meanwhile, have determined that one of those found dead at the site was not a passenger but a Libyan rescue worker who responded to the scene and died of a heart attack.
Wednesday's crash killed 103 of those on board the flight from South Africa to the Libyan capital. A 9-year-old Dutch boy who was the sole survivor returned home to the Netherlands on Saturday. His parents and 11-year-old brother perished.
Most of those on board were Dutch tourists. Lead Dutch investigator Dann Noort said Sunday that work to identify bodies has started.
