The girls school, near Nablus in the northern West Bank, was found vandalised Wednesday morning with Hebrew graffiti on the wall reading "regards from the hills." Jewish settlers live on hilly outposts nearby.
The Israeli military says it received a complaint from Palestinians and has sent officers to investigate. The fire appeared to cause minor damage.
The incident appears to be the latest action in a campaign extremist Jewish settlers call the "price tag." They say it is their response to moves by the Israeli government to remove unauthorised settlements or restrict settlement construction.
Two weeks ago, arsonists torched a West Bank mosque, scrawling "revenge" on a wall in Hebrew and charring copies of the Muslim holy book.
