Once the ban takes effect next Friday, supporting the group will become a criminal offense punishable by up to 14 years in prison.Since the outbreak of the war in Gaza, Palestine Action has targeted facilities linked to Israeli defense contractor Elbit Systems, as well as other companies with ties to Israel.
