During a protest on 20 October 2023 against the QMM Mine belonging to Rio Tinto in Madagascar, three activists and members of the LUSUD association Mr Damy, Ms Rasolonirna and Mr Andriamamonjy Jean Salomon, were shot and killed. 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.

During another protest against the mine in July 2023, arrest warrants were issued against two human rights defenders, Eugène Chretien and Laurent Manjary, from the LUSUD movement and at least 6 protesters were injured and taken to hospital and at least 75 protesters were arrested, as well as 5 trade unionists working for Río Tinto.

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.
