Mr. Lofven on Monday told the newspaper Aftonbladet that Jews were under assault from both the extreme right and the far left. He also expressed concern about what he said was rising anti-Semitism among immigrants from the Middle East.
“That goes against the very moral fiber of Sweden,” he told Aftonbladet. “Here all people have the same value.”
Mr. Lofven said that the government had allocated more money to schools for trips to Auschwitz and that stiffer punishments for anti-Semitism might be needed. “More students need to see this firsthand and be in Auschwitz, for example, or another concentration camp to really understand what has happened.”
Those who attack Jews or engage in hate speech will be brought to justice, he said.
In 2010, the Simon Wiesenthal Center, a Jewish human rights organization, issued a travel warning about Sweden because of the harassment of Jews in Malmo. The Jewish population in Sweden is about 18,000, according to the World Jewish Congress.
On Tuesday, two young men threatened the Jewish community center in Malmo. “They said they were going to throw a bomb at us,” Fredrik Sieradzki, a spokesman for the center, told Swedish Television News.
Several European countries have reported anti-Semitic protests against President Trump’s decision last week to move the United States Embassy to Jerusalem from Tel Aviv.
Mr. Lofven said the issue of anti-Semitism might be raised at the high-level European Union meeting in Brussels this week.
“It’s not on the program, but when we meet we raise relevant questions and big problems,” he said. “And this is clearly a big problem.”
