Police have said they have "heightened concern" about a possible terrorist attack on Jews in the UK.
However, the force emphasised that it has seen nothing to suggest such an attack is imminent.
In a statement issued on Friday, Mark Rowley, assistant commissioner at the National Policing Lead for Counter Terrorism, said: “The global picture of terrorist activity does give us heightened concern about the risk to the Jewish community in the UK. We are seeing continuing antisemitic rhetoric from extremists and attacks on this community in France and elsewhere.
“In addition to our existing security measures, we are in dialogue with Jewish Community leaders about further actions that we will be taking, including more patrols in key areas.
The Community Security Trust said the police had contacted them immediately before issuing the announcement to stress that there was no specific intelligence suggesting an imminent attack against the Jewish community.
CST said: “The increase in the risk assessment for the Jewish community is an appropriate and necessary response after last week’s attacks in Paris and recent anti-terror operations in Belgium and elsewhere."
It added that "increased levels of policing should be obvious in Jewish neighbourhoods throughout the UK and extra policing will be in place for other operations relating to the protection of the Jewish community.
“We hope that the increased police presence, alongside CST patrols, will help to reassure the Jewish community as they go about their lives during this difficult time.”
