Istanbul / Berlin (AP) - The Turkish President Recep Tayyip Erdogan has threatened to send a larger number of supporters of the terrorist militia Islamic State (IS) back to Europe.

Turkey has already started, Erdogan said in Ankara before traveling to the United States. The President linked the deportations and the dispute over Turkish natural gas drilling with Cyprus. "You may take it lightly. But these doors can open, "Erdogan said. "Then you can see how you manage." The EU should reconsider its attitude towards a country that has control over many IS members in Turkey and Syria. Erdogan again threatened to send migrants to Europe.

The trigger for Erdogan's statements is the discussion about possible EU sanctions for Turkish natural gas wells. The EU considers these unlawful. She cleared the way for new sanctions on Monday. Ankara rejects allegations of illegal drilling outside Cyprus.

The background of this dispute is the division of the island of Cyprus. Turkey has occupied the north of Cyprus since 1974. There is the - recognized only by Turkey - Turkish Republic of Northern Cyprus. The entire island, however, is internationally recognized as the Republic of Cyprus. She has been an EU member since 2004.

Turkey has received more than 3.6 million refugees from civil war in Syria. This week, Turkey pushes German suspected IS supporters into the Federal Republic for the first time. Erdogan said that Europe is experiencing "considerable excitement and panic" in the face of repatriations.

The CDU foreign policy politician Norbert Röttgen told the German Press Agency that it had to be made clear to Erdogan, "that for us Europeans and also for us German extortion from the outset as a method of relations is rejected." The chairman of the Foreign Affairs Committee of the Bundestag added: "We have to make it clear that we are not addressable at this level."

Domestic Affairs spokesman Mathias Middelberg told dpa: "The Turkish president's constant threats to Europe are not moving on." Finally, Turkey itself should have a significant economic interest in fruitful cooperation with the EU. Turkey and the EU should better "look ahead and work to limit migration flows".

Turkey started a military offensive against Kurdish militia YPG in northern Syria on 9 October, which it considers a terrorist organization. According to official figures, 287 IS supporters were arrested, including women and children. According to Erdogan, more than 1,000 ISIS supporters are in Turkish prisons, including 737 foreign nationals.

The YPG-led Syrian Democratic Forces (SDF) still guard thousands of ISIS prisoners in northern Syria. Pro-Kurdish media activists said on request that despite the Turkish invasion, the SDF still had control of all IS detention centers, with the exception of Ain Issa.

According to the German government, Turkey plans to deport two German IS women with a migrant background who fled Ain Issa this Friday. In the medium term, the deportation of two German converts is planned, who had also escaped from this camp in northern Syria. First of all, it should be ensured that the children who are with them are actually their own children - and thus German citizens.

As the Federal Government further announced, this week a total of ten people from Turkey are to be transferred to Germany: A man who was already flown out on Monday, according to the information has no relations in the Islamist milieu. A family of seven, who is attributed to the Salafist milieu in Lower Saxony Hildesheim, should be deported on Thursday. She had arrived in Turkey at the end of January and was detained two months later. About a possible stay of the family in the IS area is not known.

According to the Ministry of the Interior, Turkey also plans the return of eleven French and two Irish alleged IS fighters. An American and the 28-year-old Dane Ahmad al-H. have already been deported. The Dane was sentenced to four years in prison for IS membership in Turkey and is now in custody in Denmark.

The Federal Government currently knows of 133 adults from Germany who are said to have joined the IS and are in Syria, Iraq or Turkey. Of these, 95 are German citizens.

In recent years, a number of IS supporters have returned to Germany on their own initiative. As announced on Tuesday, the Federal Court in Karlsruhe rejected a complaint of the widow of the IS terrorist and former Berlin gangster rapper Denis Cuspert (aka Deso Dogg) against her imprisonment. The Attorney General had the German-Tunisian Omaima A. arrested in September - three years after her return from the IS-area.
