At least two US officials in Germany have developed symptoms of "Havana Syndrome," The Wall Street Journal reported.

US diplomats told The Journal that they sought treatment after developing symptoms including nausea, fatigue, and headaches, over the last few months.

More than 130 US personnel across the world have reported similar symptoms, as Insider's Aylin Woodward previously reported. Locations have included in Cuba, China, Russia, and the US.

These latest cases are the first reported in a NATO country that hosts US troops and nuclear weapons, The Journal reported.
