Israel plans to pull all 8,000 Jewish settlers and the Israeli troops who protect them from Gaza, while keeping control of the borders, coast and airspace.
Opponents of the plan chained the facilities in and around Tel Aviv, the BBC reported. Signs stating "Jews don't expel Jews" were hung on school gates.
"This is violent unruliness that should not be ignored," said Israeli Education Minister Limor Livnat.
Authorities had firefighters remove the chains and signs.
