Police arrested 13 people after Palestine Action activists launched a protest in Norwich on Saturday. A crowd of 100 people waved Palestine flags and held up placards that read “Stop the genocide in Gaza” and “Free Palestine” outside City Hall shortly after 1pm.

Home Secretary Yvette Cooper has defended the proscription of Palestine Action as a terrorist organisation, stating it is more than a regular protest group. Ms Cooper argued that Palestine Action has engaged in an escalating campaign of violent criminality, distinct from lawful protest.

The proscription of Palestine Action – banning membership or support for the organisation on the ground that the home secretary believes it is “concerned in terrorism” – has led to hundreds of arrests, two legal challenges and many questions about the state of protest rights in the UK.
