Israeli Education Minister Yoav Kisch on Thursday vowed to “deal with” Herzliya Hebrew Gymnasium headmaster Ze’ev Degani if the historic Tel Aviv high school continues to encourage students to evade service in the Israel Defense Forces.

“There are instances where we draw a line,” Kisch told Makor Rishon on Thursday. “Where? The Palestinian-Israeli Parents Circle-Families Forum, for example.”

On Aug. 2, the Education Ministry announced it would ban the NGO from conducting programs in public schools over allegations it whitewashes terrorism.
