Environmental activists, part of Extinction Rebellion, used harmless fluorescein dye to turn Venice's Grand Canal green.

The action was a protest against what activists perceived as insufficient progress at the COP28 climate summit in Dubai.

Protesters, suspended from the Rialto Bridge, displayed a banner with the message: "COP28: While the government talks, we are hanging by a thread."

Similar green dye protests occurred in other Italian cities, symbolising environmental concerns across the country.
Venice Mayor Luigi Brugnaro criticized the activists as "eco-vandals" and urged authorities to take punitive measures. Boat traffic on the Grand Canal was halted for safety checks.
