One hundred Nivkh, Evenk, and Uilta people of Siberia have blocked roads with their reindeer for three days in protest against the planned construction of two huge oil and gas pipelines on their land.

Leader Alexei Limanzo said the companies involved had failed to meet the indigenous peoples' demands for an investigation into the environmental effects of the pipelines, Sakhalin-1 and Sakhalin-2.
