Joining protesters around the world, campaigners from the environmental group – as well as members of the International Solidarity Network and Articulation of the Indigenous Peoples of Brazil [AIPB] – gathered at the iconic central London spot on Sunday morning.

The dramatic demonstration was held in order to draw attention to more than 600 deaths suffered by indigenous people in Brazil, as well as raise money for medical funds. Protesters also gathered to oppose the ongoing deforestation of the Amazon rainforest and associated biodiversity loss.
