Germany’s Foreign Ministry announced Thursday that the country’s embassy in Ankara has been closed for the day after it received fresh threats of a possible attack, reports said. The announcement followed the closure of the German general consulate and the German School in Istanbul earlier in the day.

German embassy officials in Ankara told Hurriyet Daily News, a local newspaper in Turkey, that the move was a “one-day precaution taken due to [an] unconfirmed indication of an attack.”

The move comes days after a car bomb attack in Ankara killed 37 people, for which the Kurdish terror group TAK claimed responsibility Thursday. The German embassy warned its citizens in Turkey to be careful, Deutche Welle, a German news agency, reported.

Turkish Prime Minister Ahmet Davutoglu is scheduled to meet leaders from the European Union in Brussels, including German Chancellor Angela Merkel, Friday. The meeting will review a draft deal between Turkey and the EU over the exchange of refugees and to lift visa travel restrictions for  Turkish citizens entering Europe, the Wall Street Journal reported.
