At least 29 children and babies have died on their way to a camp for displaced people in northeastern Syria since early December, according to the United Nations. The primary causes of the deaths are malnourishment and hypothermia. The U.N. said Friday it asked the U.S.-backed Syrian Democratic Forces to provide a safe transit site for civilians fleeing violence in the area. They said over 23,000 have fled to the camp in the past two months.
