Germany will reopen its diplomatic missions in Turkey next week, a government official said Friday, after they were shut due to a terror threat.
Der Spiegel magazine reported that the threat apparently came from Islamic State. The Germans were tipped off by US and Turkish intelligence as well as Kurdish Peshmerga forces in northern Iraq.
The diplomatic missions will reopen Monday, while the German cultural centre, the Goethe Institute, will remain shut due to a public holiday.
Meanwhile, Turkish authorities are investigating the German school in Istanbul after it was closed Thursday and remained shut Friday due to a terror threat, the pro-government Sabah daily reported.
The paper called the closure a "scandalous decision" meant to spread panic, but failed to provide details as to what authorities were investigating the school for.
The local government in Istanbul sharply criticized the move, arguing it will "negatively influence" the public.
German Foreign Minister Frank-Walter Steinmeier said the country was made aware of "very concrete" threats, which led to the decision to close the various offices.
On Sunday an attack in the Turkish capital Ankara killed 37 people. The car bombing was claimed by the hardline Kurdistan Freedom Falcons (TAK).
