The Toronto-born rabbi injured in a Jerusalem synagogue attack has died of his injuries nearly a year after being stabbed.

Rabbi Howie Chaim Rotman, 55, had been in a coma since he was critically injured in the attack in November 2014.

In the incident, two Palestinian cousins entered Har Nof shul in West Jerusalem and set about murdering the worshippers with knives, axes and guns.

Rabbi Rotman’s death on Saturday brings the death toll of the massacre to six, including a police officer.

Meanwhile, a rabbi who works for an Israeli human rights organisation was attacked during a Palestinian olive harvest last week.

Video footage of the attack shows a man, believed to be a settler, pulling out a knife and threatening Rabbi Arik Ascherman of Rabbis for Human Rights.

The attacker, wearing a balaclava, can be seen pulling out the knife and waving it as if about to stab the rabbi, before kicking and pushing him to the ground.

The masked attacker can eventually be seen running away, leaving Rabbi Ascherman to get up with minor injuries.

The rabbi had been trying to help a local Palestinian community with its annual olive harvest along with Israeli and international activists and under the supervision of the IDF.

Following the incident, Rabbi Ascherman said: “One of the masked Israelis ran toward me with big stones, started to throw stones and pulled out a knife. After a short struggle he ran away.”
