WASHINGTON (Reuters) — The United States still does not know what the illness known as Havana Syndrome is or who is responsible for it, U.S. Secretary of State Antony Blinken said in an interview on Thursday after more American diplomats were reported ill in Paris and Geneva.
Blinken said the entire federal government is working to get to the bottom of the illness, which has afflicted about 200 U.S. diplomats, officials and family members overseas.
“To date, we don’t know exactly what’s happened and we don’t know exactly who is responsible,” Blinken said in an interview with MSNBC.
The Wall Street Journal on Thursday reported additional illnesses among officials serving in U.S. diplomatic missions in Paris and Geneva, where the United States and Russia held security talks on Monday over Moscow’s troop buildup near the Ukraine border.
Blinken said the United States has discussed the illnesses with the Russians but still cannot make a determination about who was responsible.
The mysterious ailment carries symptoms including migraines, nausea, memory lapses and dizziness. It was first reported among U.S. officials in the Cuban capital in 2016.
Blinken said he has met with State Department employees around the world who described the illnesses and how these incidents disrupted their lives.
“There is no doubt in my mind that people have been directly and powerfully affected,” he said.
“We are working overtime across the entire government to get to the bottom of what happened, who’s responsible. And in the meantime to make sure that we’re caring for anyone who’s been affected and to protect all of our people to the best of our ability.”
