Residents of Venice, Italy woke up to a mysterious bright green patch of water in the city’s central waterway on Sunday.
The phenomenon could be seen along an embankment near the Rialto Bridge, which expanded throughout the day. The incident has sparked an investigation involving the police, the local environmental agency, and other local bodies.
Luca Zaia, head of the Veneto region, tweeted that an “urgent meeting” had been convened to discuss the green swath of water.
