Four people were killed when a helicopter crashed on Saturday in the forested mountainous area of Tijuca National Park in Rio de Janeiro, Brazil, authorities told AFP. The victims included three Colombian women from the same family who were visiting the city as tourists. Firefighters said three women and the pilot died after being burned in the crash.

The helicopter went down near the Vista Chinesa area, on a remote and steep mountainside. Firefighters released images showing smoking wreckage. Colombia’s consul general in Rio de Janeiro, Diana Paez, said the three women had travelled to the city with relatives to celebrate a teenager’s 15th birthday.

The six-member family had split into two groups because the helicopter could carry only three passengers at a time. Paez said the teenager’s grandmother, aunt and a cousin were among those killed; her father and his companion were due to take a later flight. Colombia’s consulate assisted Brazilian authorities with identification, which was difficult because of the condition of the bodies. Rio Mayor Eduardo Cavaliere called for stronger safety oversight.
