Police used tear gas and water cannons to disperse violent demonstrators in Rome as tens of thousands of pro-Palestinian protesters took to the streets in major European cities and around the globe Saturday to call for a cease-fire as the first anniversary of the Hamas attacks on Israel approached.

The war in Gaza, which started on 7 October last year, has seen more than 41,000 Palestinians killed and decimated the Strip. Almost 100 Israelis are still being held hostage by Hamas, with fewer than 70 believed to be alive.

The protest was part of an international day of action from dozens of organizations commemorating a year of the conflict that began Oct. 7, 2023.
