The demonstration took place in Trafalgar Square, where hundreds of protesters gathered to oppose the government’s move and express support for the group. According to London’s Metropolitan Police, those detained were arrested for showing support for a “proscribed organization”.
Authorities said the action was taken under laws that restrict public backing for organizations listed under anti-terrorism legislation. The protest was the first major gathering after London’s High Court ruled in February that the ban on Palestine Action as a terrorist organization was unlawful.
However, Britain’s Interior Minister Shabana Mahmood has received approval to challenge the court’s decision through an appeal.
As of 14:50hrs officers have made 92 arrests, all for showing support for a proscribed organisation.

The ages of those arrested range from 27 - 82.
Officers are continuing to make more arrests and a group remains in Trafalgar Square.
Palestine Action has repeatedly accused the British government of supporting Israel and being complicit in what it describes as Israeli war crimes in Gaza. The group has been involved in several high-profile demonstrations in recent years.

Last July, British lawmakers officially banned Palestine Action under anti-terrorism laws. The decision came after some activists linked to the group reportedly broke into a Royal Air Force base during a protest action.
Israel has consistently rejected allegations that it committed abuses during its military operations in Gaza. During the protest in Trafalgar Square, many demonstrators held placards and banners criticizing the ban.
Several protesters also wore traditional black and white Palestinian scarves and waved Palestinian flags. Some participants sat on the ground or used folding chairs while chanting slogans and calling for the government to reverse the ban.
Police monitored the protest closely and eventually carried out mass arrests, making it one of the largest protest-related arrests in recent years in London. The incident has sparked renewed debate about freedom of protest and national security laws in the United Kingdom.
Supporters of the protesters argue that people should have the right to express political views peacefully. Meanwhile, government supporters say strict laws are necessary to prevent extremist activities.
