More than half of the estimated 300,000 Syrian refugees who have fled to Lebanon are not receiving the medical treatment they need because of high costs, Doctors Without Borders (MSF) said on Thursday. In a report entitled "Misery beyond the war zone," MSF gave the results of a survey carried out in the southern city of Sidon, the eastern Bekaa Valley and the northern city of Tripoli, where its teams are providing free medical care.
