BERLIN (Reuters) -German police said on Friday they are investigating several cases of so-called Havana syndrome at the U.S. Embassy in Berlin, a mysterious ailment believed to have affected 200 U.S. diplomats, officials and family members worldwide.

The syndrome - with symptoms including migraines, nausea, memory lapses and dizziness - came to public attention in 2016 after dozens of diplomats at the U.S. Embassy in Havana, Cuba, complained of the sickness.
