White House acknowledges mysterious health attacks occurred in US, reviewing intel on incidents

Dozens of U.S. officials have been affected, but there's still no known cause.

The mysterious health incidents that have affected dozens of U.S. personnel around the globe have also occurred within the United States, the White House confirmed for the first time on Friday. The source of the illnesses, known as "Havana syndrome" after the first cluster of cases at the U.S. Embassy in Cuba, is still unknown. But there is growing pressure from Congress to figure out what has affected so many U.S. diplomats, spies and other officials -- and who or what is behind it. "At this point, at this moment, we don't know the cause of these incidents, which are both limited in nature and the vast majority of which have been reported overseas," said White House press secretary Jen Psaki, acknowledging the newly reported cases in the U.S. The Biden administration has launched a review of U.S. intelligence to determine if there are other previously unreported cases and if there is a "broader pattern," a National Security Council spokesperson confirmed to ABC News.
