U.S. military planes are transporting contractors and supplies to Haiti, preparing for a security mission led by Kenya. The deployment, estimated at $600 million, faces funding challenges. Flights from South Carolina have landed in Port-au-Prince, with contractors securing the airport for the international security force. The deployment, delayed by legal obstacles, is now set for a 2,500-member force, including police from Kenya and personnel from other nations. The mission aims to address the crisis in Haiti, plagued by gang violence and food shortages. The U.S. has pledged $300 million, but funding approval is pending. The UN fund has $18 million, with additional support from Canada and in-kind donations. The mission's timing is expected to align with a state visit by Kenya's president in late May.
