Hundreds of people attended a pro-Palestine protest in Belfast city centre, calling for the removal of the ban on Palestine Action.
The group was proscribed by the UK government as a terrorist organisation in July.
The ban means membership of, or support for, the group is a criminal offence under the Terrorism Act 2000, with membership of the group carrying a maximum sentence of 14 years in prison.
Around 20 police officers were present at the Belfast demonstration while a number of police vehicles could be seen at a distance.
A small number of protesters displayed posters and placards in support of Palestine Action.
People also wore t-shirts in support of the group.
No arrests were made this evening.
