Protester Denis McDermott, 73, from Edinburgh, said he had been arrested before and had no hesitation in coming forward again.
“I’m a supporter of these great people,” he said, waving to other protesters, adding that if the court process had been certain “there would have been no need for all this”.
Protest organizers Defend Our Juries said hundreds of people took part in Saturday’s demonstration, protesting “the UK government’s complicity in Israel’s genocide in Gaza and its misguided crackdown on peaceful protests at home”.
“Despite the High Court declaring the government’s ban on the group illegal and leading lawyers warning that any arrests would be illegal, police were choosing to make arrests,” it said in a statement.
Amnesty UK condemned the arrests as “another blow to civil liberties in this country”.
