Haiti’s main international airport has reopened nearly three months after gang violence forced authorities to close it. The reopening Monday of the Toussaint-Louverture airport in Port-au-Prince is expected to help ease a critical shortage of medications and other basic supplies. The country’s main seaport remains badly affected. Gangs control 80% of the capital. U.S.-based airlines are not expected to start using the airport until late May or early June. In recent weeks, U.S. military planes have landed with civilian contractors to help Haiti prepare for the arrival of foreign forces expected to help quell the violence.
