A rabbi was left "bleeding and dazed" after an anti-Semitic assault by two attackers who shouted "kill the Jews".
The senior religious leader, who was visiting the UK for a family wedding, was thrown to the ground by two men on Clapton Common in Stamford Hill on Friday night.
Security group Shomrim said that he had left the Bobov Synagogue in Egerton Road and was walking along Clapton Common when he was approached by the men.
They repeatedly punched him, threw him to the ground and carried on beating him, only stopping when a member of the public intervened.
Shomrim said the rabbi, who sits in a Judaic court as a judge, was left "collapsed on the pavement, bleeding and dazed where he lay for several minutes".
He has since flown back to Israel and is said to be traumatised by what happened.
The attackers were described as young, slim, black men who were wearing hooded tops. One was wearing grey trousers and white trainers.
Rabbi Herschel Gluck, who works with Shomrim, said the victim was left "bruised and traumatised" by his ordeal.
