Yemen's Saudi-backed government has proposed reopening the Houthi-held airport in the capital Sanaa on condition planes are inspected in the airports of Aden or Sayun which are under its control, two government officials said on Friday. For more on this issue, Asher Orkaby from Harvard University joins CGTN for discussion. He's a research fellow in the study of the conflicts in Yemen and wrote the book, "Beyond the Arab Cold War: The International History of the Yemen Civil War, 1962 to 68."
