Havana, July 11 (RHC)-- The Cuban Foreign Ministry has issued a statement calling on the U.S. government to stop the "political manipulation" of alleged health issues.

A fourth meeting was held in Washington D.C. Tuesday between authorities from law enforcement agencies from Cuba and the United States, the Cuban foreign ministry said, adding that joint investigations by the agencies from both countries have found no evidence of the alleged sonic attacks against U.S. diplomats in Havana.

The statement said that the Cuban delegation urged the United States government to stop its hostile behavior and “political manipulation” towards the Caribbean country using “the alleged health incidents that became a pretext to adopt new unilateral measures that affect the operation of the respective embassies, particularly, the rendering of consular services depended upon by hundreds of thousands of people.”

The meeting was concluded with an agreement to “continue with this dialogue and to keep holding the technical meetings between the law enforcement agencies from both countries to bring bilateral cooperation to fruition,” the statement of the Cuban ministry said.

Last year, so-called 'sonic attacks' led to the withdrawal of U.S. diplomatic staff in Cuba, after 24 staff displayed concussion-like symptoms, according to the State Department. No evidence was ever found to support the allegations.
