A Bell 407 helicopter with five people aboard went down on Wednesday in Venezuela's southwestern Andean region, officials said, according to Xinhua.
It was unclear whether there were any survivors, Venezuelan Interior and Justice Minister Tarek El Aissami told reporters.
Aissami said the weather and geographic conditions of the area where the chopper fell were complicated, and a rescue team had been sent to search for possible survivors.
The copter probably went down due to bad weather, he said.
Regional Civil Protection Director Alfredo Jaczko said the helicopter, with two crew members and three passengers on board, was making a supervision trip at the hydroelectric dam Uribante Caparo. The accident occurred near the city of Uribante which borders Colombia.
