Former Justice Minister Tzipi Livni said in a statement on Sunday night that Defense Minister Moshe Ya'alon's move to name anti-assimilation group Lehava a terrorist organization needed to be done months ago, adding that now is better than never.
"This organization works from hatred, racism and nationalism and its goal is to bring an escalation of violence within us," she said.
Three members of the group were indicted last month for allegedly setting an integrated Jerusalem school on fire and spray-painting anti-Arab graffiti there.
Ten more of the group's members, including its leader Bentzi Gopstein, were arrested days later for incitement.
Lehava propagates the racist ideology of the late Jewish Defense League founder Meir Kahane, who was assassinated in New York City in 1990 after his radical Kach Party was outlawed in Israel for inciting racism.
