Kenyan police officers have arrived in Haiti to lead a UN-backed mission aimed at combating armed gangs that have seized control of Port-au-Prince, with doubts emerging about their effectiveness as the gangs threaten more violence. The Haitian Prime Minister, Garry Conille, departed for Washington and New York amidst the deployment, where important meetings with international officials are scheduled. Port-au-Prince residents express cautious optimism, hoping the Kenyan forces can bring lasting security, given the country's history of challenges after previous international missions. The mission, requested in 2022, aims to address widespread issues including indiscriminate killings, kidnappings, and mass violence, with the UN estimating millions struggling for basic needs and internal displacement.
