London’s Metropolitan Police arrested at least 200 people on Saturday during the largest pro-Gaza demonstration in central London, organized in support of "Palestine Action", a group banned by the UK government last month under the so-called “anti-terror” laws.

Police said they expect to carry out more arrests in Parliament Square, while organizers emphasized that those detained represent only a “small fraction” of the hundreds who took part in the protest.

Despite the peaceful and public nature of the demonstration, police claimed that many in the square were mere "spectators" rather than participants, and threatened to arrest anyone holding a sign in support of Palestine Action—a move widely seen as a blatant crackdown on free speech and solidarity.

The event was organized by Defend Our Juries, a grassroots campaign group that has been escalating its efforts under the slogan “Lift the Ban”, calling for the UK government to reverse its decision to outlaw Palestine Action.

In a statement, the group accused the police of obstructing their right to organize peaceful opposition to the ban and revealed that their website was taken offline earlier in the week by a hosting provider—yet another apparent attempt to silence dissenting voices.
