On 1 June Colombians, Latin Americans, British people, and people from other countries peacefully gathered outside the Colombian embassy in London in solidarity with the people of Tolima, Colombia, whose livelihoods are under threat by the devastating consequences posed by the La Colosa gold mining project.  Earlier on the same afternoon, a protest was held outside the Peruvian embassy, a short distance away, against environmental and human rights abuses of multinational mining companies in Peru.
