The school allows its pupils to take part in field-training trips, during which they spend a night in a base and undergo physical drills and weapons training. The outings are seen as a treat for students, and those with bad grades are not allowed to go. The school is named after the Russian imperial general Alexei Yermolov and many of its students are from military backgrounds. Photographs by Eduard Korniyenko. --Reuters (17 photos total)

Many indigenous groups, including the Huni Kui, Ashaninka, and Madija, live in villages in the Brazilian rainforest near the border with Peru. Over the past three years, the Ashaninka and Madija say that they have seen more and more incursions on their territory from uncontacted tribes, defined by Survival International as groups who have no peaceful contact with mainstream society. The "Bravos," or "Braves," as uncontacted Indians are called in the region, carry out raids on other villages, putting the communities along the Envira River on permanent alert. Leaders of the Ashaninka tribe have asked the government and NGOs for help in controlling what they consider an encroachment on their area by these uncontacted indigenous groups, stating that the movement of these other tribes is the result of pressure caused by illegal logging across the border in Peru.
