Authorities are continuing to investigate the incident and working to track down the occupants of the vehicles through license plate identification, though it's unclear how many of the cars belonged to the already identified victims killed or injured, all of whom were airlifted to hospitals following the accident.
Police are using drones to inspect the area and find any other possible missing people as the search and investigation continues.

Officials have not revealed the nationalities of the known casualties in relation to the accident and rescue crews with dogs were unable to continue their search on Monday (July 4) as conditions in the area were too dangerous.
