Activists across several European countries held demonstrations on Saturday to express solidarity with the Gaza Strip and to protest the arrests of the activists in the Global Sumud Flotilla aid mission.

In the UK, protests took place in London, with a major demonstration in Trafalgar Square condemning the ongoing war on the besieged enclave, leading to the arrest of several protesters by British police, including elderly individuals.

Arrests made in Trafalgar

Additional protests were held in the same city to oppose the government's move to proscribe the group Palestine Action as a "terrorist organization".

Police began arresting demonstrators at the silent vigil in support of the group.

Dozens of police were lined up to begin arresting members of the group, who were sitting silently on the pavement in the square.

It comes as the chair of the Metropolitan Police Federation has claimed “enough is enough,” as she said officers policing protests in London were “emotionally and physically exhausted."

'It’s unconscionable'

One protester, Trudy Warner, a retired social worker from London, was holding a sign reading “Police find your love, find your conscience.”

She said she was focusing on the police because they were able to take action as individual officers and not participate in the mass arrests.

“I would love to think they could learn from us about the power of collective action and walk away instead of doing this because it’s unconscionable. It’s actually unconscionable.”

Italy sees widespread protests, strikes

Thousands of people across Italy, including in Rome, Milan, and Bologna, have taken to the streets to protest "Israel's" seizure of a Gaza-bound aid flotilla and the detainment of dozens of Italian nationals.

In Rome, an estimated 20,000 protesters, many of them students, marched with Palestinian flags and banners reading "Against Genocide". Similarly, large demonstrations were held in Milan, where organizers estimated a turnout of 50,000, and in Bologna, where over 10,000 people participated.

In response to these events, Italian trade unions called for a general strike, with the Unione Sindacale di Base (USB) declaring a nationwide strike for October 1, directly citing the reports of the aid flotilla being raided. 

Further escalating the labor action, Italy's largest trade union, the CGIL, also made a declaration on October 26. The union stated that it would call for a general strike if the humanitarian flotilla to Gaza were to be blocked or attacked in the future, signaling a continued commitment to the cause.

'Israel' hijacked Sumud flotilla in international waters

On October 2, the Israeli Navy seized all 42 boats from the Global Sumud Flotilla, preventing life-saving humanitarian aid from reaching Palestinians in Gaza, as "Israel" sustained its illegal siege and engineered famine in the Strip.

Hundreds of participants from the flotilla were transported to the port of Isdud, where they were given the choice between voluntary deportation or undergoing legal procedures for forced repatriation to their home countries, according to a report by Israeli Kan military correspondent Itay Blumenthal. 

According to a report from the flotilla organizers, more than 443 participants from 47 countries were illegally detained by Israeli authorities following the seizure of the fleet, which prompted it to call for urgent international intervention to ensure the safety of the volunteers and secure their immediate release.

Ben-Gvir takes swing at Netanyahu

Israeli Police Minister Itamar Ben-Gvir sharply criticized Prime Minister Benjamin Netanyahu’s decision to deport the activists of the Global Sumud Flotilla, who were detained while attempting to reach the Gaza Strip to break the blockade.

On October 3, while speaking to the press and describing Netanyahu’s decision to allow the flotilla participants to return to their countries as “a fundamental mistake", Ben-Gvir argued that the detainees should have been imprisoned in “Israel” for months.

“They should be kept in Israeli jails to smell the suites in which the terrorist prisoners are kept. Sending them back time after time only encourages their return," the Israeli far-right minister stated.
