Thousands of Indigenous people marched through Brasilia on Tuesday, denouncing land rights violations they link to farming, logging and mining projects.

The protest followed the Esplanade of the Ministries to Three Powers Square, seat of government. It forms part of the Free Land Encampment, Brazil's largest Indigenous mobilisation, gathering around 7,000 people from 200 groups for a week of coordinated demands.

Leaders also urged Luiz Inácio Lula da Silva to act, warning that support for oil projects risks clashing with pledges on Indigenous rights. Activists cite rising invasions by miners and loggers, and violence in areas such as Bahia.

Researchers say protecting Indigenous territories remains one of the most effective ways to curb deforestation in the Amazon rainforest, a key regulator of the global climate.
