Activists from the Extinction Rebellion movement have been accused of killing fish in the river and fountains of a French town with a bright green dye that they poured in the water to protest against a toxic waste project.
Éric Straumann, the mayor of Colmar, an Alsatian town whose waterside district is known as Little Venice, said dozens of dead fish were found floating on the surface after the protesters dumped drums of fluorescein in the River Lauch at the weekend.
