The International Organization for Migration (IOM) reports that more than 20,000 people have been forced to flee Haiti's capital Port-au-Prince in just four days, including more than 17,000 sheltering in 15 displacement sites, as gang violence escalates. In a statement on Sunday, the UN organization said the current crisis has disrupted critical supply chains and isolated the city as criminal groups in the capital continue to expand and take control of more neighborhoods.
