Police have made 150 arrests as protesters gathered in central London to show support for Palestine Action in defiance of its ban as a terror group.
Defend Our Juries, which organised the demonstration, said between 600 and 700 people were in Parliament Square on Saturday afternoon.
The Metropolitan Police said it would arrest anyone expressing support for Palestine Action.
The crowd, sat on the grass inside Parliament Square, could be seen writing “I oppose genocide, I support Palestine Action” on white placards at 1pm, with the vast majority remaining silent.
Several demonstrators carrying placards that read “Palestine Action terrorises Britain while Hamas hides in hospitals, schools and mosques”, briefly walked along the crowd before being led away by police officers.
Other clusters of protesters who were not holding placards gathered around the Mahatma Gandhi and Nelson Mandela statues in the square singing pro-Palestinian chants.
Arrest update: We’ve now arrested 150 people in Parliament Square.

While many of those remaining in the Square are media and onlookers, there are still people holding placards supporting Palestine Action.

Officers were holding individual demonstrators sat on the edge of the grass before escorting them through swelling crowds to police vans parked on the edge of the square.
A separate group of officers attended a protester lying next to the fenced-off Emmeline Pankhurst statue.
They later began arresting protesters sat in the middle of Parliament Square.
The officers lifted the protesters – some sitting and some lying flat – off the ground before escorting them away.
Onlookers applauded the protesters and shouted “Shame on you” at the police making arrests.
Protesters who were still sat in the middle of Parliament Square stood up together at 2pm and held their placards in the air.
One person was also arrested at a separate Palestine Coalition march, which set off from Russell Square heading to Whitehall via Aldwych and the Strand.
The arrest was “for a placard showing support for Palestine Action”, Scotland Yard said.
Membership of, or support for, Palestine Action is a criminal offence punishable by up to 14 years in prison under the Terrorism Act 2000.
Earlier this week, the first three people to be charged with supporting Palestine Action in England and Wales were named.
Jeremy Shippam, 71, Judit Murray, 71, and Fiona Maclean, 53, have all been charged with displaying an article in a public place, arousing reasonable suspicion that they are a supporter of a proscribed organisation after their attendance at a previous demonstration last month.
Hundreds have been arrested in the wave of Defend Our Juries protests across the UK since the ban was implemented by Home Secretary Yvette Cooper last month.
A Home Office spokesperson said: “The Home Secretary has been clear that the proscription of Palestine Action is not about Palestine, nor does it affect the freedom to protest on Palestinian rights.
“It only applies to the specific and narrow organisation whose activities do not reflect or represent the thousands of people across the country who continue to exercise their fundamental rights to protest on different issues.
“Freedom to protest is a cornerstone of our democracy and we protect it fiercely.
“The decision to proscribe was based on strong security advice and the unanimous recommendation by the expert cross-government proscription review group.
“This followed serious attacks the group has committed, involving violence, significant injuries and extensive criminal damage.”
