At least six people die after two helicopters collide in mid-air and crash in the western zone of Rio de Janeiro, Brazil, local fire services say. Firefighters report that the aircraft go down in the parking lot of an electric vehicle dealership, where a fire ignites and spreads to at least 20 vehicles. Initial reports point to a mid-air collision. Fire officials confirm that all six fatalities are crew members of the helicopters. One helicopter is found on fire in the dealership parking area with five victims inside, while a second helicopter is found about 100 meters away with only the pilot onboard, who also dies. The incident takes place in the suburb of Recreio dos Bandeirantes. Rio de Janeiro Mayor Eduardo Cavaliere says there are foreign nationals on board one of the aircraft, though no further details are provided. Fire service spokesman Lieutenant Colonel Fabio Contreiras tells media that the exact sequence of events is not yet clear, citing scattered wreckage and saying investigators need recordings and videos to understand what happened. Authorities are investigating the cause of the crash.
