The area that became a refugee camp for Syrian residents back in 2014 is now the US-controlled zone. Moscow and Damascus are blaming Washington for its refusal to release residents of the camp, turning them in fact into hostages.
In January, the World Health Organization described people residing in the camp as "trapped," adding that they live "in deplorable conditions." Limited water supply, bitterly cold weather and poorly functioning health care facilities contribute to the rise of diseases, which include influenza, measles, tuberculosis and chronic respiratory diseases, according to the organization.
