As Israel’s offensive in Gaza nears its one-year anniversary, thousands of demonstrators took to the streets in major European cities on Saturday, calling for an immediate ceasefire and an end to arms sales to Israel.

London witnessed one of the largest demonstrations, with hundreds of thousands marching from Russell Square to Downing Street. This marked the 20th national protest since the Gaza offensive began. Former Scottish First Minister Humza Yousaf joined the march, defending the event against accusations of promoting hate.

Protesters across Spain, led by civil society groups and left-wing political parties, launched three days of protests in over 50 cities, including Madrid and Barcelona. The crowds chanted slogans such as “This isn’t a war, it’s genocide” and “From the river to the sea, Palestine will be free.”

In Stockholm, demonstrators marched to the Swedish Foreign Ministry, denouncing Israel’s actions as genocide and calling for lasting changes to bring peace to the region.

In Hamburg, around 950 people peacefully protested, while in Paris, thousands gathered at Republique Plaza, waving Palestinian flags and calling for an end to the violence.

Protests extended beyond Europe, with demonstrators gathering in New York’s Times Square and other cities around the world. In the Philippines, activists protested near the U.S. Embassy, although police prevented them from approaching the building.

Despite a UN resolution calling for a ceasefire, Israel’s offensive continues, with over 41,800 people killed and nearly 97,000 injured in Gaza over the past year, according to local health authorities.
