A hotel in Germany's northern port city of Hamburg has cancelled Foreign Minister Mevlut Chavushoghlu's planned conference on March 7, citing security concerns.

Axar.az reports thatç Coşkun Akgul, head of Overseas Election Coordination Center of the Justice and Development Party (AK Party), claimed that Germany was deliberately trying to prevent Chavushoghlu from meeting with Turkish citizens before Turkey's referendum on constitutional reform.

Akgul argued that hotels in Hamburg were put under pressure and warned beforehand, saying the election coordination center had already reached an agreement with the Hotel Elysee and even made a down payment, before the hotel cancelled the event on Thursday.

The hotel refused to rent out its conference room, despite the coordination center providing additional private security guards.

Other hotels also refused providing a place for the foreign minister's meeting using security issues or occupancy as an excuse, Akgul said.

Officials of the AK Party Overseas Election Coordination Center booked a Turkish wedding saloon in Hamburg's Veddel neighborhood for the event.

Foreign Minister Chavushoghlu's meeting will take place next Tuesday at 06.00 p.m. local time. Entrance to the event at the Saray wedding saloon will be free of charge.

Chavushoghlu's upcoming visit to Hamburg was also widely covered by German media and political parties, including the Left and the Green parties.

Prime Minister Binali Yıldırım and his German counterpart Angela Merkel held a phone call on Saturday amid a diplomatic spat between the two countries after Thursday's controversial ban on meetings of Justice Minister Bekir Bozdagh and Economy Minister Nihat Zeybekci in Germany.
