JERUSALEM (AP) -- Israeli police say they are investigating anti-Arab graffiti found on Muslim tombs in central Jerusalem.
Police spokesman Micky Rosenfeld says vandals scrawled "price tag," the signature of radical Jewish activists. He says police found the graffiti Thursday, but it is believed to be several weeks old.
Vandals have desecrated some Muslim and Christian holy sites in both the West Bank and Israel. In October, vandals torched a mosque in northern Israel.
Rosenfeld says the police have dedicated a task force to eradicating extremist attacks.
Police arrested an Israeli man Wednesday on suspicion of spraying graffiti and calling in a bomb threat to the Jerusalem offices of Peace Now, an Israeli movement that opposes Israeli settlements in the West Bank.
