A Jewish-Arab bilingual school and a Christian monastery in Jerusalem were defaced with graffiti on Tuesday in suspected "price tag" attacks by Jewish extremists.
"Death to Arabs" and "Kahane was right" were scrawled in Hebrew on a wall outside the bilingual school.
"Death to Christians" was written on the walls of the Greek monastery, an 11th-century fortress-like holy site in a valley overlooked by Israel's parliament. The tires of two cars outside the monastery were punctured.
Jerusalem police are investigating both incidents, and are still unsure whether they are connected.
The bilingual school is a symbol of coexistence in Jerusalem. Half the students are Jews and half are Arab, and they study together in both languages.
"It wasn't just written here, where young children from the ages 3 to 18 study together in coexistence, for no reason," said principal Nadia Knani. "We are trying to digest this horrifying incident."
Police spokesman Micky Rosenfeld said vandals had also scrawled "price tag" on the monastery.
Attacks on Christian shrines in Jerusalem are rare.
The slogan, used by Jewish settlers in vandalism attacks on mosques and Palestinian homes in the West Bank, refers to the retribution they say they will exact for any attempt by the Israeli government to curb settlement.
"I am a priest and I forgive," said Father Claudio of the monastery, which is administered by the Greek Orthodox church.
