Tens of thousands of people have marched in cities across Europe, denouncing Israel’s genocidal war on Gaza and demanding tougher global action against its continued and deadly violations of a United States-brokered ceasefire.

The demonstrations, held to mark the United Nations International Day of Solidarity with the Palestinian People on Saturday, came as the death toll from Israel’s war on Gaza surpassed 70,000 people.

The latest victims include two boys, aged eight and 10, who were killed in an Israeli drone attack on the town of Bani Suheila, east of Khan Younis in southern Gaza.

In the French capital, Paris, an estimated 50,000 marched along the city’s major streets, chanting “Gaza, Gaza, Paris is with you” and “From Paris to Gaza, resistance!”.

They also waved Palestinian flags while denouncing “Israeli genocide”.

“This is not acceptable. We are still so far from justice or accountability,” one protester told Al Jazeera.

“We, the people, know that this [Israel’s war] is wrong. But why do the people in power not feel that this is wrong?” asked another protester.

Anne Tuaillon, head of the France Palestine Solidarity Association (AFPS), one of about 80 non-government organisations, unions and parties behind the call to protest, said that “nothing has been resolved” seven weeks after a ceasefire took effect on October 10.

“The ceasefire is a smokescreen. Israel violates it every day, blocks humanitarian aid and continues to destroy homes and infrastructure in Gaza. We are calling for a permanent ceasefire and an end to the genocide,” she told the AFP news agency.

Protests were also held in London, Geneva, Rome and Lisbon.

Al Jazeera’s Sonia Gallego, reporting from Paris, said that for the organisers, the march represents a “sustained pressure” on Israel at a time when negotiations for a more lasting peace in the Palestinian territory remain stalled.

“This worldwide mobilisation is not just maintaining focus on Gaza, but also [on] the broader unresolved issue of Palestinian rights.”

In the British capital, London, organisers said that up to 100,000 joined the march demanding accountability for Israeli “crimes” against Palestinians and pleading for “protection” of those still suffering under siege despite a ceasefire.

In Italy, where mass demonstrations and union-led strikes have repeatedly mobilised against Israel’s war, the UN’s special rapporteur on the occupied Palestinian territory, Francesca Albanese, and climate activist Greta Thunberg, attended the main demonstration in the capital, Rome.

The Wanted In Rome news website, in a report ahead of the rally, said some 100,000 were expected to take part.

In a statement posted on X, Albanese said that Israel is “committing genocide against the Palestinians” not just in Gaza, but in the occupied West Bank, too.

“Look at the totality of conduct/crimes against the totality of the Palestinians in the totality of the land slated for ethnic cleansing. Israel must be stopped, and we will,” she wrote.

Under the US-brokered ceasefire, Israel has pulled back to a so-called “yellow line” inside the Gaza Strip. But it remains in control of more than half of the besieged territory, and has launched several deadly attacks in breach of the agreement.

Since the ceasefire deal, at least 500 Israeli violations have been recorded, resulting in at least 347 Palestinians being killed and 889 being injured.

Fadi and Jumaa Tamer Abu Assi were aged eight and 10, respectively.

Alaa Abu Assi, an uncle of the two boys, said they were “innocent children who have no rockets and no bombs”.

“They were gathering firewood to help their disabled father, who has platinum plates in his legs. We went and found them in pieces, and we brought them back,” he told the AFP news agency.

In a statement, UN Secretary-General Antonio Guterres said that “the killing of so many civilians, the repeated displacement of an entire population and the obstruction of humanitarian aid should never be acceptable”.

Al Jazeera’s Hind Khoudary, reporting from Gaza City, said that even as Palestinians welcome the international support, most “are simply trying to survive”.

“It’s a daily struggle,” she said. “Palestinians are suffering to get their basic necessities; they’re suffering to find shelter.”

“There are lots of Palestinians still living in tents. They’re saying that they do not have any source of shelter. There’s no medication. Their children are without any education. The Palestinians are still dying slowly, despite the fact that it is ceasefire,” she added.

On Thursday, rights group Amnesty International warned that “Israeli authorities are still committing genocide” in Gaza, waging new attacks and curbing critical aid access, despite the declared ceasefire.
