On Friday, Russia and Syria sent convoys to the Rukban camp, which houses around 40,000 displaced people, so that the refugees could return to the places of their permanent residence.
In January, the World Health Organization (WHO) 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, the WHO stated.
