London police has approximated that around 100,000 people participated in the "March for Palestine" protest, expressing their opposition to Israel's ongoing bombing campaign and complete blockade of Gaza

Ben Jamal, director of the Palestine Solidarity Campaign, said in a post on X: “We are all united to deliver the same message: we want the violence to end. We’re calling for an immediate ceasefire and for necessary humanitarian supplies to be safely delivered to the people of Gaza.”

With chants of "Free Palestine," banners held high, and Palestinian flags waving, the demonstrators proceeded through London, eventually gathering at Downing Street, which serves as the official residence and office of British Prime Minister

Authorities in Gaza say more than 4,300 people have been killed in the territory since the latest war began. More than 1,400 people have been killed in Israel, mostly civilians slain during Hamas’ deadly incursion on Oct. 7

Israel continued to bombard Gaza on Saturday ahead of an expected ground offensive. A small measure of relief came when 20 trucks carrying humanitarian aid were allowed to enter Gaza across the southern Rafah border crossing with Egypt.

The war has raised tensions around the world, with both Jewish and Muslim communities feeling under threat. The British Transport Police force said it was investigating after footage was posted online that appears to show a London Underground driver leading passengers in a chant of “Free, free Palestine” over the subway intercom.

Hundreds of pro-Palestinian protesters also gathered in Belfast and in Northern Ireland’s second city, Londonderry, where speakers included lawmaker Colum Eastwood of the Irish nationalist Social Democratic and Labour Party

“The murder of children is wrong,” he told the crowd, calling for an immediate cease-fire in the conflict. “I don’t know how that is so difficult for some of our world leaders to actually utter. It doesn’t matter whether they are Israeli children or Palestinian children.”

Across the border in the Republic of Ireland, thousands marched through the capital, Dublin, calling for an end to Israel’s bombardment

In France, pro-Palestinians demonstrators gathered in several cities including Rennes, Montpellier, Dijon and Lyon, where thousands of people could be seen chanting “we all are Palestinians” in the central square.

In Marseille, the country’s second-largest city, some people took to the streets, waving Palestinians flags and shouting “Free Gaza,” despite the protest being banned by local police.

German police said almost 7,000 people took part in a peaceful pro-Palestinian demonstration in Düsseldorf on Saturday. The demonstrators carried Palestinian flags or banners calling for an end to “violence and aggression in Gaza.”

Police in Berlin banned a pro-Palestinian demonstration that was scheduled for Sunday in the center of the city, German news agency dpa reported. Police in the German capital have stopped several similar events in recent weeks, citing the potential of violence and antisemitic hate speech. Some pro-Palestinian demonstrators have taken to the streets anyway, resulting in clashes with police.
