Police said victims could not be formally identified yet as they were badly burned in Sunday’s crash in the Brazilian city
The helicopters crashed into the car park of an electric car showroom, igniting a fire that engulfed at least 20 cars.
A statement from firefighters said initial reports pointed to a mid-air collision, adding “six fatalities have been confirmed, all were crew members of the aircraft involved in the accident”.
Rio de Janeiro Mayor Eduardo Cavaliere said there were “foreign nationals on board one of the aircraft”, without giving further details.
Police said American alternative singer and internet personality Oliver Tree is listed as one of six people on the manifest shared by a police source, who said the victims could not be formally identified yet as they were badly burned in the crash.
Fire services spokesman Lieutenant Colonel Fabio Contreiras told CNN Brasil at the scene that it was unclear exactly how the accident unfolded.
