The warning follows an arson attack on Jewish community ambulances in London earlier this month.

Four vehicles operated by the volunteer-led Hatzola service were set alight, prompting a response from officials in both countries.

Two men were arrested in connection with the incident and later released on bail.

Israeli foreign minister Gideon Sa’ar discussed the issue in a phone call with UK foreign secretary Yvette Cooper, describing the spread of antisemitism as “spreading like wildfire.”

He also called for action to tackle the problem at its source.

Prime Minister Sir Keir Starmer called for communities to “all stand together”.

Official figures show Jewish people had the highest rate of religious hate crimes targeted at them of any faith group in the year to March 2025, according to data published by the Home Office.

Mr Sa’ar said: “Antisemitism in the UK, as well as in other countries, is spreading like wildfire and requires treatment at its roots.”

He referenced a recent comment piece by former prime minister Tony Blair, who warned that some on the political left wrongly portray the Jewish community as supporters of the Israeli government, making them, in his words, “fair game.”

The Community Security Trust (CST), a charity monitoring antisemitism in the UK, recorded 3,700 anti-Jewish hate incidents in 2025.

This figure represents a four per cent rise from the 3,556 incidents recorded in 2024 and marks the second-highest annual total on record.

CST pointed out that 2023 remains the worst year on record, with 4,298 incidents reported, the year of the October 7 attack, which prompted a spike in recorded cases of anti-Jewish hate in the UK.

The charity’s 2025 report also noted that more than 200 antisemitic incidents were recorded in every month of the year for the first time.

In October 2025, two people were killed in an attack on a synagogue in Manchester.

Earlier this month, two men were charged with allegedly spying on Jewish people and locations in the UK on behalf of Iran.

The government has pledged to continue funding the Jewish community protective security grant, allocating £28 million for the next financial year.
