The German Foreign Ministry issued a warning on Wednesday to tourists in Istanbul of possible terror attacks in the metro and at bus stops. "Trips around the country [Turkey] should be carried out with particular carefulness and caution. There are indications of possible terrorist attacks in the metro and bus stops in Istanbul," the ministry said in a statement.
The ministry warned its citizens in Turkey to stay away from the borders with Syria and Iraq, in particular, from cross-border facilities and recommended tourists constantly monitor current events in the country through media and their own countries' diplomatic missions.
The statement comes after a surge in terrorist activities in Turkey, including a suicide bombing in the Turkish border town of Suruc that killed 32 people, primarily Kurds, and injured over 100, and the killings of two police officers in the southern city of Ceylanpinar.
