 Gang violence in Haiti has displaced more than 300,000 children since March, according to the United Nations Children Agency, as the Caribbean country struggles to curb killings and kidnappings. The UN says children are more than half of the nearly 580,000 people who have become homeless in the last four months. The spike in violence began in late February after a series of coordinated attacks on key government infrastructure eventually led Prime Minister Ariel Henry to resign in April.
