Inside a camp for Yemeni refugees who have fled to Djibouti

Fighting on Yemen's west coast has driven thousands to flee by boat across the Bab al-Mandab Strait to Djibouti in the last ten days, after an Iran-backed Houthi offensive to seize the port of Mokha and a key island. The BBC's Frank Gardner visited a camp in Obock, where officials are preparing for up to 10,000 refugees. The UN International Organisation for Migration said people are arriving on overcrowded boats with very limited food and water.
