Germans have worn skullcaps in marches across the country a day after Jews were warned not to wear the kippah following a spate of anti-Semitic attacks.

Rallies in solidarity with the Jewish community were planned in Berlin and in the cities of Cologne, Potsdam, Magdeburg and Erfurt.

German newspapers, including Die Tageszeitung, urged readers to join the protests - with some including cut-out skullcaps for people to wear.

It comes a day after the head of Germany's Central Council of Jews, Josef Schuster, warned against wearing religious symbols on city streets for fear of attack.

His warning came a week after a 19-year-old Syrian refugee attacked two young men wearing kippahs in a trendy district of the capital, shouting 'yahudi' - Jew in Arabic - and lashing out at his victim with a belt.

A video of the assault, filmed by one of the Israeli victims, went viral on social media and sparked widespread revulsion.

The recent spate of anti-Semitic incidents has raised pointed questions about Berlin's ability to protect its burgeoning Jewish community seven decades after the Holocaust.

'We must never allow anti-Semitism to become commonplace in Germany again,' Foreign Minister Heiko Maas told the daily Tagesspiegel ahead of a 'Berlin Wears Kippah' event where Jews and non-Jews will wear the traditional skullcap in a shared show of defiance.

Every attack on Jewish life 'is an attack on us all', Maas added.

The issue of anti-Semitism is particularly fraught in Germany, which has gone to great lengths to atone for its Nazi past and whose political class takes deep pride in the growth of the now 200,000-strong Jewish community.

However, a number of high-profile incidents in recent months have stoked fears of a possible resurgence of anti-Semitism from both the far-right and a large influx of predominantly Muslim asylum-seekers since 2015.

In March, the Central Council of Jews urged schools to keep track of religious bullying following reports that a young Jewish girl was harassed by Muslim fellow pupils at a Berlin primary school and allegedly received death threats after she said she didn't believe in Allah.

Earlier this month, two rappers raised hackles by winning a music prize after selling more than 200,000 copies of their album which features a lyric boasting that their bodies are 'more defined than Auschwitz prisoners'.

The far-right Alternative for Germany party, which captured nearly 13 percent of the vote in September's general election, has also not shied away from questioning Germany's cherished 'remembrance culture'.

Party member Bjoern Hoecke last year called Berlin's Holocaust memorial a 'monument of shame' and said Germany should take a '180-degree' turn away from its guilt over World War II crimes.

Chancellor Angela Merkel on Sunday denounced the emergence of 'another form of anti-Semitism', beyond that of right-wing extremist groups, from Muslim refugees, in an interview with Israeli television.

She reaffirmed that the security of Jews and of the state of Israel was a central concern for Germany because of its 'eternal responsibility' for the Holocaust in which the Nazis murdered six million European Jews.

However, Schuster of the Central Council appeared to question that assurance Tuesday with a stark warning that Jews who wear the kippah or the Star of David could be courting danger on German streets.

The remarks sparked outrage, with the Nazi-hunting Simon Wiesenthal Center accusing German authorities of failing to take effective action against violent hate crimes.

'When the respected head of German Jewry feels it necessary to urge Jews to hide their identities in public, it is clear that German authorities have failed to protect the rights of their Jewish citizens and are failing to counter growing anti-Semitism,' Rabbi Abraham Cooper of the Los Angeles-based association said.

The head of the European Jewish Association, Rabbi Menachem Margolin, criticised Schuster, saying he was 'mistaken in the cure for the serious problem'.

'Not wearing a skullcap due to fear of anti-Semitism is in fact the fulfilment of the vision of anti-Semites in Europe,' he said.

The International Auschwitz Committee, founded by survivors of the Nazi death camp, welcomed Wednesday's kippah demonstrations but said they must be part of a broader effort by German officials, teachers and average citizens.

'That would make this day an important first step -- a break with the past,' its vice president Christoph Heubner said.
