Americans traveling to some parts of Russia are at risk of being kidnapped, the U.S. State Department said in an updated travel advisory on Tuesday.

Russia was listed alongside Sudan and Niger as one of the most dangerous countries for U.S. travelers in the State Department’s new risk-based system in January 2018. Moscow dismissed the system — which upgraded Russia alongside Italy, Spain and France in December 2018 — as a scare tactic at the time.
