(Financial Times) – For more than a decade, Mohammed Hassan felt secure in his job inspection and offloading goods as food, oil and medicine were shipped into the Red Sea port of Hodeida. Yemen’s largest cargo port has long been the main artery for the country and Mr. Hassan always believed ships would dock there, even as conflict tore this nation apart. Then in November, the Saudi led-coalition, which supports Yemen’s exiled government in a civil war with Iranian-aligned Houthi rebels tightened its sea blockade of the country.
