Climate activists darken Trevi Fountain water in Rome protest.

Seven young activists from the Ultima Generazione group poured diluted charcoal into the Trevi Fountain in Rome to turn the water black in protest against climate change and public subsidies for fossil fuels. The group called for an end to public subsidies for fossil fuels and linked the protests to deadly floods in the northern Italian region of Emilia-Romagna in recent days. Rome mayor Roberto Gualtieri condemned the protest, the latest in a series of acts targeting works of art in Italy.
