Drone video shot by the Turkish Humanitarian Relief Foundation gives a sense of the immense scale of the refugee crisis at the Turkey-Syria border, where tens of thousands of Syrians are holed up.

The footage shows aerial views of dozens of white tents housing refugees escaping civil war in their home country. Turkish officials have said that around 100,000 Syrian refugees are being cared for in nine camps inside Syria near the Turkish border. A 10th camp is being built two miles inside of Syria.
