On the morning of 25 March 2021, a group of miners broke into the premises of the Munduruku Wakoborũn Indigenous Women's Association and set fire to documents, office materials, furniture and pieces of indigenous handicrafts. The incident was reported to police, however an investigation has yet to be opened into the incident. The premises had been rented by the Association since December 2020 and was used to provide services to indigenous peoples. The facility was shared with other organizations such as the Da'uk Association, the Arikico Association, the Munduruku Ipereg Ayu Movement and CIMAT. The miners had come from a protest organised by a group of miners against the indigenous community’s opposition to the mining in the area. During this protest, and reportedly on numerous other occasions, the miners issued death threats to members of the Association and other indigenous women who have opposed the illegal mining. Violence has been escalating in the Munduruku territory since 14 March 2020, when a large amount of equipment for gold exploration was discovered on the territory. On 19 March, 2020, a group of armed men prevented indigenous people from accessing the land. A helicopter suspected of serving as a convoy for miners working on the illegal excavations has also been filmed flying over the area. The miners have also been reportedl using different underhanded tactics to encourage the Munduruku indigenous peoples to support them in attacking the territory. Munduruku leaders have also been the target of ongoing threats and attacks.
