Seven people have been charged in Britain in connection with activities linked to the banned group Palestine Action, which was outlawed in July after activists broke into the country’s largest air base and damaged military aircraft.
The ban makes it a criminal offense to join or support Palestine Action, placing it in the same legal category as groups such as Hamas, al Qaeda, and ISIS.
The decision has drawn criticism, including from the United Nations human rights chief.
Six suspects, aged between 26 and 62, were arrested on Tuesday in London as part of a Counter Terrorism Command investigation by the Metropolitan Police.
They were remanded in custody and are due to appear in court on Thursday. A seventh person was charged separately in Scotland on Tuesday in a related case.
Detective Chief Superintendent Helen Flanagan said the charges followed a proactive investigation into suspected activity connected to the group.
She stressed that anyone showing support for Palestine Action could face arrest and prosecution.
The Metropolitan Police said more than 700 people have been arrested and over 100 charged in relation to protests this summer, many of them targeting companies linked to Israeli weapons production.
Palestine Action has been granted a High Court hearing in November to challenge its proscription, but the judge has declined to suspend the ban until then.
