Indians in Peru have surrounded three oil wells in the country's northern Amazon jungle run by Argentina's Pluspetrol. At the time of writing around 40 workers are trapped inside the facilities.
The Indians are protesting against decades of water pollution which they allege is ruining their health and the environment.
Roberto Ramallo, the company's local director, told Radioprogramas radio late Wednesday night, "I want to clarify that in reality, please, for the tranquillity of their families, they are not being held hostage...They are simply inside their offices of the Pluspetrol camps. They do not have the possibility to leave because the entrances are blocked."
He added "At no time has there been physical violence."
