Macedonian authorities imposed further restrictions Sunday on refugees trying to cross the border from Greece, allowing only those from cities they consider to be at war to enter, Greek police officials said. The officials said the restrictions mean people from cities such as Aleppo in Syria, for example, can enter Macedonia at the Idomeni border crossing, but those from the Syrian capital of Damascus or the Iraqi capital of Baghdad are being stopped. The two officials spoke on condition of anonymity because they weren't authorized to speak on the record. The restrictions were the latest move by Macedonia to slow the flow of refugees into the country, and come a day ahead of a summit between the European Union and Turkey to discuss the crisis, AP reported.
