"We witness the Islamophobes and members of the PKK [the Turkish Kurdistan Workers' Party banned in Turkey] attacking mosques and our citizens. We are very concerned about that. Today the German ambassador in Ankara was summoned to the Turkish Foreign Ministry, where he was given a note and received the necessary warnings," Bozdag told reporters.
According to Bozdag, Ankara is asking the German government to take measures to protect Turkish citizens living in Germany.
German media earlier reported that unidentified assailants last Friday set a mosque on fire in the town of Lauffen am Neckar in Baden-Württemberg.
A similar incident occurred on Sunday in Berlin's northern borough of Reinickendorf, where a mosque and a Turkish cultural center were set ablaze.
