The British police said the attack on Wednesday was being treated as terrorism, and they warned of rising antisemitic hate crimes.

Officials are investigating similar attacks across Europe, all claimed by a shadowy Islamist group that may be using low-cost, unsophisticated methods to sow fear in Jewish communities.

A Jewish security group told police an attack on the community was “likely” because of heightened antisemitism, days before December’s mass shooting in Sydney.

In guidance to immigration officers, the administration describes participating in pro-Palestinian protests and criticizing Israel as “overwhelmingly negative” factors.

Prime Minister Keir Starmer’s government blocked the artist formerly known as Kanye West from entering Britain for the three-day Wireless Festival in July.

The police said the men, aged 45 and 47, were accused of arson with intent to endanger life after the attack on Monday in Golders Green.

The city’s main police force said it was investigating fires that struck four ambulances as an antisemitic hate crime.

A German court found that the attacker, now age 20, had traveled more than 100 miles to stab a Spanish tourist, who survived.

The country and its small Jewish community are still trying to process the mass shooting at Bondi Beach in December.

The temple said 20 shots were fired at the building but no one was hurt.
