A helicopter carrying a team filming for an MTV reality show has crashed in western Argentina, killing at least two people.
The Bell 206 helicopter crashed on Saturday as it flew over the reservoir at Potrerillos de Mendoza dam about 1000km northwest of Buenos Aires, Gianni Vernier, security minister for Mendoza province, told the state news agency Telam.
Vernier said the pilot and a technician died, but it was not immediately known if other people were in the helicopter.
Searchers were trying to reach the wreckage, which was 60 metres below the surface, he said.
It was the second deadly helicopter accident this year in Argentina involving a reality show.
Last March, two helicopters working on the TV survivalist show Dropped collided while filming over rugged terrain in northwestern Argentina and all 10 people on board died.
Among the dead were three noted French athletes - pioneering sailor Florence Arthaud and Olympian swimmer Camille Muffat and boxer Alexis Vastine.
