Sunday marked the second day of attacks on the United Nations humanitarian convoy attempting to bring desperately needed food and hygienic supplies to the city of Homs. On Saturday, a convoy was attempting to evacuate more civilians, but attacks prevented aid from coming in and trapped a U.N. team. “This was a day in hell,” said Yacoub El Hillo, head of the U.N.'s aid and development effort in Syria. He did not say who targeted the convoy, but other U.N. Officials said it was pro-government forces who attacked them. President Bashar al-Assad only agreed to allow the aid in after heavy pressure from allies Iran and Russia.” If it was up to me, I wouldn't let any food in or allow anyone out," said one senior Syrian military officer.
