In July 2023, two members of the LUSUD association, Eugène Chretien and Laurent Manjary were issued with arrest warrants following a protest that blocked the main road to Rio Tinto’s QMM mine in Madagascar. This protest follows a compensation and indemnification payment offer by the mining company, which affected communities say falls short of the value of the losses suffered in terms of their environment, health, and lives.

The LUSUD association was created in March 2023 to focus on the high risks of contaminated water consumed by communities due to the untreated wastewater from the Rio Tinto QMM mine.

The Business & Human Rights Resource Centre invited Rio Tinto to respond to these allegations. It's responses and rejoinders from civil society organisations Publish What you Pay Madagascar and the Andrew Lees Trust can be found here.
