Germany announced Tuesday that a parliamentary delegation is expected to visit Turkey between May 25 and May 28 following the April 16 constitutional referendum.

The delegation consists of four German deputies and is headed by the Vice President of the German parliament Claudia Roth, who is a member of the Green Party.

Refugee expert Luise Amtsberg from the Green Party, Matthias Zimmer from the Christian Democrats (CDU) and Foreign Affairs Specialist Niels Annen from Germany's Social Democrats (SPD) will also be part of the delegation.

The delegation will meet representatives from the Turkish Grand National Assembly (TBMM) executive board, the Foreign Ministry and the Ministry of EU Affairs in Ankara and then travel to Turkey's southeastern city of Diyarbakır to come together with members of non-governmental organizations.

The ministers will end their Turkey visit in Istanbul, where they will meet various artists and academics, the parliamentary statement elaborated.

The statement added that the delegation was not visiting the Incirlik Air Base in southern Adana province.

Tension between Turkey and Germany rose last week after a German parliamentary delegation was not allowed to visit the Incirlik Air Base, where German troops are stationed.The move was in response to Germany's attitude towards Turkish deputies during the recent constitutional referendum period.

German-Turkish relations have been strained over the past months, after German local authorities canceled public appearances of Turkish ministers and government officials campaigning ahead of the April 16 referendum in several German towns and cities, based on poor excuses such as the inadequacy of parking lots and security concerns, while allowing pro-PKK events and Turkish opposition officials to rally for the "No" campaign.

In addition, Germany's uncooperative stance with regard to the Gülenist Terror Group (FETÖ) has also been a source of tension as the country has been a safe haven for hundreds of FETÖ members, including high ranking NATO military officers.

The two countries went through the same crisis almost a year ago. A German parliamentary defense commission delegation was not allowed to pay a visit to the Incirlik Air Base after the German parliament adopted a controversial resolution regarding the events of 1915.

Since 2015, Germany has stationed around 260 troops, six high-tech Tornado surveillance jets and a tanker aircraft at Incirlik Air Base.
