A pipeline in Canada has leaked an estimated 200,000 litres of oil in an aboriginal community, the provincial government has said.
The government was notified in the late afternoon on Friday.
Around 170,000 litres have since been recovered.
The incident happened in the western Canadian province of Saskatchewan.
The spill comes seven months after another incident in the same area, in which a Husky Energy pipeline has leaked 225,000 litres into a major river and cut off the drinking water supply for two cities.
It is not yet clear how the immediate incident happened or which company owns the underground pipeline leaked the oil.
