A Venezuelan indigenous leader who was an opponent of armed groups and illegal mining has been shot dead in the Amazonas state capital, a non-governmental organization and three people with knowledge of the case said. Virgilio Trujillo Arana, a 38-year-old indigenous Uwottuja man, was a defender of the Venezuelan Amazon and had set up community groups to act as guardians of the Autana municipality of Amazonas. Arana was shot in the head three times by a gunman who fled to a waiting vehicle in Thursday’s attack in the city of Puerto Ayacucho. He had reportedly received threats relating to his work.

The Uwottuja community is made up of about 15,000 people.

Communities from the town of Uwottuja announced last February their decision to defend their territory against a “silent invasion” by criminal groups, rejecting illegal mining exploitation as well as the use of their land for illicit activities. Mining has been prohibited since 1989 in Venezuela’s southern Amazonas state, which is not part of the so-called Arco Minero, or Mining Arc, a gold exploitation zone 111,000 sq km created by decree in 2016 by the government of President Nicolas Maduro. The office of United Nations high commissioner for human rights Michelle Bachelet has asked the government to regularize mining activities and guarantee that they are carried out under international and environmental standards.
