Rabbi peace activist beaten up by extremist Israeli settlers

Rabbi Moshe Yehudai, a peace activist, was beaten with an iron rod by five extremist settlers, their faces hidden by masks, while trying to protect Palestinian olive farmers. The assault comes during a severe spike in settler violence that has even included attacks on Israeli soldiers. Settler leaders have voiced condemnations, but Israeli human rights groups say that the impunity of these young extremist settlers shows the obstacles that stand in the way of any peaceful resolution to the conflict. CNN's David McKenzie reports.
