An indigenous leader was killed and another was injured when loggers allegedly ambushed them in the northeastern Brazilian state of Maranhao. The attack happened on Friday when two members of a group known as "Forest Guardians" left their village in search of water. Five armed men approached and immediately started shooting at them, according to the Human Rights Secretary of Maranhao. The Guajarara are an indigenous tribe that works to protect the rainforest. The group has been continuously threatened by loggers who experts say have taken advantage of reduced controls and less oversight to seize control of forest lands.
