(KGTV) - The U.S. State Department issued a travel warning Friday for Americans going to Cuba after mysterious illnesses at the U.S. Embassy in Havana.
Over the summer, embassy employees were targeted in specific attacks, the State Department said.
Employees reported a wide range of physical symptoms including ear complaints, hearing loss, dizziness, headaches, fatigue, cognitive issues and difficulty sleeping.
Attacks have also occurred in U.S. diplomatic residences and hotels frequented by U.S. citizens, officials said.
The State Department said Friday that because it had not been able to identify the source of the attacks, the department believes U.S. citizens may also be at risk and it is warning them not to travel to Cuba.
