After months of investigation, U.S. officials concluded that the diplomats had been attacked with an advanced sonic weapon that operated outside the range of audible sound and had been deployed either inside or outside their residences. "Cuba is universally considered a safe destination for visitors and foreign diplomats, including U.S. citizens," the statement said. U.S. officials say their diplomats in Havana were attacked with an advanced sonic weapon. Like all foreign diplomats in Cuba, the victims of the attacks lived in housing owned and maintained by the Cuban government. Nauert said the department had reminded Cuba of its international obligation to protect foreign diplomats.
