BUENOS AIRES, Argentina (AFP) — Two helicopters collided in mid-air Monday in northern Argentina, killing 10 people including cast members filming a French reality show, officials said.

“There are several French nationals among the victims. So far we only know of two Argentine victims,” La Rioja province government spokesman Disel Cuneo told AFP.

Another provincial spokesman, Horacio Alarcon, said that the two helicopters appeared to have collided during filming.

“There are no survivors,” he added.

Alarcon said the weather conditions were good and the cause of the crash was unknown.

The crash happened in a mountainous part of La Rioja, whose scenic landscapes are popular with tourists, around 1,100 kilometers (700 miles) north of the capital Buenos Aires.

Argentine media showed the wreckage of the two helicopters in flames on the dry scrubland.
