U.S. officials are still investigating health problems at the U.S. embassy in Cuba, and do not know who or what was behind the mysterious illnesses, which began in 2016 and have affected 26 Americans.
“We don’t know who is responsible and we don’t know what is responsible for this,” Kenneth Merten, Acting Principal Deputy Assistant Secretary for Western Hemisphere Affairs, told a House of Representatives Foreign Affairs Committee hearing.
The administration of President Donald Trump, which has partly rolled back a detente with Cuba, responded to the health problems by sharply reducing staff in Havana and in October expelled 15 Cuban diplomats.
