A senior UN official on Monday said Colombia needs international help as it struggles with a humanitarian catastrophe along its border from Venezuelans driven from their homes by hunger. David Beasley is Director of the World Food Programme and he made the comments after meeting refugees during a visit to Cucuta in eastern Colombia. He told The Associated Press that the harrowing reports he heard makes raising awareness of the humanitarian crisis an urgent priority. He plans to work with Colombia to feed the 50,000 Venezuelans entering the country each day.
