"An Arab stabbed him in the neck," spokesman for the United Hatzalah of Israel rescue organizationYerach Tucker told Ynet. "The guard chased him, but he managed to escape. MDA and United Hatzalah teams treated the rabbi before he was evacuated to the Hadassah Ein Kerem Medical Center." MDA Paramedic Ilan Klein told Ynet: "We found a 50-year-old man bleeding from the neck after being stabbed, but fully conscious. He said he was stabbed from behind and didn't see his assailant. Immediately after he was stabbed he continued walking for a few meters until he encountered a police officer.

We administered first aid, gave him IV and oxygen and evacuated him to the hospital." Jerusalem Mayor Uri Lupolianski denounced the stabbing and called on police and security forces to find the assailant as soon as possible. Lupolianski added that he sees what he called the attempts made by radicals to hurt the fabric of coexistence in Jerusalem, as very grave. Less than two weeks ago, eight people were killed and 10 were wounded in a shooting attack at Mercaz Harav yeshiva in Jerusalem. The terrorist who carried out the attack had been killed. The Shin Bet security service has recently received seven warnings regarding possible attempts by terror organizations to carry out attacks over the Purim holiday this weekend. "Any Israeli holiday is a sensitive period, as terror groups' motivation to launch attacks is especially high during this time," a senior security official said. "Therefore, the alert level of the entire security establishment will be very high." Aviram Zino, Neta Sela and Yaron Druckman contributed to the report
