Rabbi Menachem Margolin, the association’s general director, said EU leaders had not done enough to combat antisemitic attacks and prejudices in the lead-up to the attacks on Saturday – one on a free speech debate and one on a synagogue – and pointed to a need to “secure all Jewish institutions 24/7”.

As the Danish prime minister, Helle Thorning-Schmidt, condemned what she called “a cynical act of terror”, senior rabbis and Jewish politicians from around Europe expressed their solidarity with the Danish people and gave voice to rising fear and paranoia amid their own communities.

“The Jewish community in the city is really tense,” Copenhagen’s Chabad House rabbi Yitzhak Leventhal told Israel’s Channel 2 news. “This is an attack on the right of Jews to exist here.”
