LONDON: British authorities have charged six people for participating in meetings to plan a demonstration in support of the banned group Palestine Action, prosecutors said Wednesday.

The six, aged from 26 to 62, were charged “with various offenses of encouraging support for a proscribed terrorist organization,” the Crown Prosecution Service said in a statement.

They were placed in detention and are due to appear in court on Thursday. They risk up to 14 years in prison.

Palestine Action was designated a terrorist organization and banned in July after vandalism at a Royal Air Force base.

The charges result from 13 online meetings they attended to prepare for several protests over the summer.
