"We now have new phenomenon in having refugees or people of Arab origin who are bringing another form of anti-Semitism back into the country. This dismays us." — German Chancellor Angela Merkel.

In his first media interview as the new head of the influential GdP police union in North Rhine-Westphalia (NRW), Michael Mertens was asked if there are any no-go zones in NRW, Germany's most populous state. He replied: "There are areas where police do not go alone, only in large teams. Such areas are now present in almost all NRW cities."

One of Germany's leading economists, Hans-Werner Sinn, warned that the migrant crisis could end up costing German taxpayers more than one trillion euros: "The cost to the taxpayer could also be higher. So far, there are about 1.5 million migrants who have come to Germany since 2015. And no: They are not dentists, lawyers and nuclear scientists, but mostly underqualified immigrants, who have arrived in the promised land... where the standard of living without employment is higher than in many countries of origin with employment."

April 1. Senior German officials, including Chancellor Angela Merkel and President Frank-Walter Steinmeier, always quick to outdo each other with good wishes for Islamic festivals, failed to greet Germans for Easter, the most important Christian festival. By contrast, Aiman ​​Mazyek, the head of the Central Council of Muslims in Germany, did offer Easter greetings: "I wish you all peaceful and relaxing holidays. Happy Easter to the Christians, a happy 'Passover' to the Jews and a few contemplative days to the non-believers. #Variety makes you strong."

April 2. German churches were sheltering 611 illegal migrants at the end of March, up from 530 at the end of December 2017.

April 9. North Rhine-Westphalia's Integration Minister, Joachim Stamp, announced a proposal to prohibit girls under the age of 14 from wearing headscarves to school. Amid a public outcry, Stamp quickly appeared to retreat: "The goal," he said, "is not necessarily a law."

And no: They are not dentists, lawyers and nuclear scientists, but mostly underqualified immigrants, who have arrived in the promised land — one flowing with milk and honey and where the standard of living without employment is higher than in many countries of origin with employment."

April 11. Der Tagesspiegel published an exposé about the bullying of German students at the hands of Muslims in Berlin schools:

"I'm in seventh grade at a high school in Schöneberg. There I am marginalized because I am German and eat pork. I am cursed in Turkish and Arabic. In German, I am insulted as a son of a bitch or f**ked whore. In addition, I am sometimes beaten and kicked. If I get too close to other boys, they call me gay and kick me. Girls in my class are called sluts when they wear strapless shirts. I've been trying to change school for many months but cannot find an empty slot. The Education Department and the school do not help me."

April 11. Alexander Dobrindt, a leading member of the Christian Social Union (CSU), a political party based in Bavaria, said that Islam "has no cultural roots in Germany." He added:

"Islam has no cultural roots in Germany and with Sharia as a legal system, it has nothing in common with our Judeo-Christian heritage. No Islamic country on earth has developed a comparable democratic culture like the ones we know in Christian countries."

April 11. A food bank in Essen called Essener Tafel resumed offering food to migrants after a three-month ban.

At the moment, 56% are Germans, compared to just 25% in January.

April 12. Kollegah and Farid Bang, a Muslim rap duo accused of singing anti-Semitic lyrics, was awarded Germany's top music prize, the Echo Music Award. The prize, awarded on Holocaust Remembrance Day, sparked public outrage. Justice Minister Heiko Maas said that "anti-Semitic provocations do not deserve a prize; they are repugnant." In an essay for Die Welt, comedian Oliver Polak wrote that the normalization of anti-Semitism in popular music was part of the reason "that young Jewish people are chased around and beaten up in schoolyards." After an extraordinary meeting in Berlin, Echo's organizer, the Federal Association of the Music Industry (BVMI), announced the end of the music award.

German authorities launched a crackdown on Middle Eastern crime families in Essen, a city in North Rhine-Westphalia where some 70 Turkish, Kurdish and Arab-born clan members regularly engage in racketeering, extortion, money laundering, pimping and trafficking in humans, weapons and drugs. Middle Eastern crime clans now control large swathes of German cities and towns — areas that are effectively lawless and which German police increasingly fear to approach. The crime families, which are believed to have thousands of members, have for decades been allowed operate with virtual impunity: German judges and prosecutors were unable or unwilling to stop them, apparently out of fear of retribution.

April 12. The Interior Ministry reported that only ten of the more than 750 Islamist Gefährder (potentially highly dangerous persons) known to be residing in Germany have been deported during the past year.

Facebook said the comment violated its "community standards," but the court ruled that it was protected by the right to free speech.

The assault, a video of which went viral on social media, highlighted the growing problem of Arab anti-Semitism in Germany. Chancellor Angela Merkel said: "This is a terrible incident.

April 24. In his first media interview as the new head of the influential GdP police union in North Rhine-Westphalia (NRW), Michael Mertens was asked if there are any no-go zones in NRW, Germany's most populous state. He replied:

April 26. Sibel H., a German-Turkish woman from Hesse, and Sabine S., a convert to Islam from Baden-Württemberg, returned to Germany on a flight from Baghdad after having joined the Islamic State in Syria. The Federal Prosecutor's Office had requested arrest warrants for the two women, but the Federal Court of Justice (Bundesgerichtshof) ruled that the women should go free because no specific terrorist membership or support had been proven. The court treats males and females differently when assessing membership of or support for the Islamic State: male jihadis fight, torture or murder, while female jihadis mainly take care of the household, bear children and care for husbands and offspring. According to the Federal Court, such acts are not punishable because they do not constitute explicit support for terrorism.

"I hear this from my own Jewish friends. But we must do everything to avoid that." Klein also said that anti-Semitism in Germany is being fueled by mass migration from the Muslim world: "There is a tendency — anti-Semitic sentiment is more openly expressed. Anti-Semitism among Muslims and the extreme right and left existed before. But it is being expressed more unashamedly. Yes, the situation has become worse."
