Police make 12 arrests as demonstrators defy government restrictions to gather on Thames embankment.

Hundreds gathered in central London for the annual Al-Quds Day demonstration, an international show of solidarity with Palestinians that this year took place under sweeping new restrictions and a heavy police presence.

Crowds assembled on Sunday along the Albert Embankment of the River Thames, where demonstrators waved Palestinian flags, held banners, and chanted slogans – some carrying images of Iran’s late Supreme Leader Ayatollah Ali Khamenei, who was killed earlier this month during US-Israeli attacks on Iran.

Police made 12 arrests during the event, including for showing support for a proscribed organisation and threatening or abusive behaviour.

Chants of “from the river to the sea” and “Israel is a terror state” were heard. Al-Quds Day is named after the Arabic name for Jerusalem.

More than 1,000 officers were deployed across the area ahead of what police Assistant Commissioner Ade Adelekan warned would still be “a difficult public order weekend”. Earlier estimates suggested 12,000 people could attend, but only hundreds showed up.

The demonstration marked the first time in more than a decade that authorities banned the march through the capital.

Home Secretary Shabana Mahmood approved Scotland Yard’s request for a month-long prohibition on marches, with the government citing public disorder risks linked to the “volatile situation in the Middle East”, and potential clashes between different groups of demonstrators.

Organisers from the Islamic Human Rights Commission proceeded with a “static” rally in defiance, telling supporters the event would go ahead regardless.

The group accused London police of having “capitulated to the pressure of the Zionist lobby”.

‘Words have consequences’

Al-Quds Day takes place annually on the final Friday of Ramadan, with rallies held worldwide in solidarity with Palestinians and in opposition to Israel’s occupation of Palestinian territory. It was held on Sunday in London as Friday was a regular workday.

Police put demonstrators on notice that “intifada” chants and displays of support for proscribed groups would result in arrest, with Adelekan stating “these words have consequences”.

On the opposite bank, a smaller counterprotest organised by Stop The Hate and the Lion Guard of Iran drew Iranian dissidents and others opposed to the Islamic Republic, some waving Israeli flags.

Scotland Yard used the River Thames as a physical barrier, with police boats patrolling the water and Lambeth Bridge closed to separate the two sides.

Both demonstrations were confined to the stretch between Vauxhall and Lambeth bridges and permitted only between 1pm and 3pm.

Both demonstrations wrapped up at 3pm, with police saying the security plan had worked and neither side attempted to breach conditions by marching.
