The Community Security Trust has issued a warning to Jewish organisations over security arrangements in the wake of the terror attack in Woolwich.
In a bulletin sent to over 1,000 groups, the CST urged that procedures at all communal buildings and events should be reviewed and fully implemented following the brutal murder of a soldier in a London street by Islamist terrorists.
While it stressed there was no evidence to suggest that the community would be targeted, it noted that “those who are willing to attack soldiers can also move to attacking Jews”.
In Toulouse, in March 2012, the murder of French soldiers by an Islamist terrorist was followed by his killing of three children and a rabbi at a Jewish school.
CST said it had been consulting with police and Minister for Communities Don Foster over possible tensions between Jews and Muslims.
Meanwhile Israeli Prime Minister Benjamin Netanyahu has emphasised Israel's solidarity with Britain in the aftermath of the attack.
"We've experienced such horrors here, and we sympathise deeply. We are both facing this battle against this savagery and terrorism in our own countries and throughout the world," he told visiting British Foreign Minister William Hague.
President Shimon Peres sent a letter of condolence to the Queen.
In the UK, Board of Deputies President Vivian Wineman expressed sympathy with the family of the murdered soldier. He said: "Our thoughts are with the victim of the horrific and barbaric murder, and with his family. We stand with other faith groups in deploring violence in the name of religion."
