A fresh human catastrophe is building up on the only open Syrian-Turkish border terminal of Bab al Salama, as a huge stream of refugees presses forward in flight from the victorious advance of the Syrian army and allied forces toward Aleppo in the north. The Turkish prime minister estimates that at least 70,000 Syrian refugees have reached the terminal or are on their way. Refusing them entry, Turkey is setting up a huge tent city along the frontier. Turkish President Tayyip Erdogan Friday accused Russia of invading Syria and held the Assad regime responsible for 400,000 Syrian deaths. He said Moscow was making Syria a “boutique state” for Bashar Assad.
