Communal organisations are monitoring the security situation in the UK, after a gunman took five people hostage in Paris today.
The Community Security Trust is liaising with UK police, government and the SPCJ, the French-Jewish security watchdog.
A spokesman for the CST said: "There will be increased policing in Jewish neighbourhoods for this weekend’s Sabbath. CST will also increase its own security at synagogues, and has issued advisory notices to all Jewish community venues and their security officers.
"These attacks are a dreadful reminder of the deadly threat that terrorism poses today. Jews are repeatedly included amongst the targets of Jihadist terrorism and this is why CST has been on its second highest level of alert for a number of years now, with the highest level being reserved for when an actual attack against British Jews has occurred, or is known to imminent.
"CST encourages British Jews to report any suspicious activity and antisemitic incidents as soon as possible to CST and police. In an emergency, police should be contacted immediately on 999."
Mike Freer, the Tory MP Finchley and Golders Green, said: “Borough Commander had confirmed that additional officers will be patrolling around synagogues to reassure local Jewish community”.
In a statement, the Board of Deputies said: “We are closely monitoring the situation in France where a number of hostages have been taken at a kosher supermarket in Paris. We are in close contact with our counterparts in France, the Conseil Représentatif des Institutions juives de France (Crif), and stand in steadfast solidarity with the French Jewish community at this difficult time.”
Chief Rabbi Ephraim Mirvis tweeted: "Let's say Shabbat Shalom with all our hearts - may this Shabbat see a peaceful end to the dramas unfolding in Paris."
