Attackers scrawled racist graffiti on a playground at a bilingual Jewish-Arab school over the weekend, Israeli police said Sunday, in the second such incident targeting the Jerusalem institution.
Police spokeswoman Luba Samri said unknown attackers had spraypainted "Death to Arabs" and "Kahane was right," on the school's playground in the Arab east Jerusalem neighbourhood of Beit Safafa.
"Kahane" is a reference to Meir Kahane, the founder of an extremist anti-Arab Jewish movement called Kach, which is officially outlawed in Israel.
Kahane was assassinated in 1990, but his ideology continues to find favour among some of Israel's most extreme right-wing settlers.
Samri said an investigation had been opened into the incident, the second time the school has been targeted in less than a week.
On February 7, attackers painted the same phrases on a wall of the school, a rare institution where students -- both Arabs and Jews -- study in both Arabic and Hebrew.
The incidents are the latest in a spate of so-called "price tag" attacks, usually carried out by extremist settlers in response to Israeli government action against settlements in the West Bank.
Attackers have targeted Palestinian and Arab property and buildings, including mosques, as well as Israeli military bases and left-wing Israeli activists.
