The earthquakes struck as fighting continued along the Turkey-Syria border between Turkish forces and Kurdish fighters. The United Nations reports more than 4 million people in northwest Syria where the deadly earthquake struck already rely on humanitarian assistance. The U.N.’s humanitarian coordinator for Syria said Monday the quake is preventing aid workers from accessing northern Syria through the single border crossing into the region.

El-Mostafa Benlamih: “The infrastructure is damaged. Roads that we used to use for humanitarian work are damaged. We have to be creative in how to get to the people and how to get to them the assistance.”
