The United States, UK, and Australia have started to withdraw the family members of embassy staff in Ukraine, as tensions between Russia and NATO countries continue to rise. On Monday, January 24, NATO confirmed that member countries had sent additional ships and jets to enhance deployments in Eastern Europe. In turn, the Kremlin's spokesman accused the alliance of provoking "an escalation of tensions." Meanwhile, the ruble's exchange rate against the U.S. dollar dropped significantly, prompting Russia's Central Bank to halt foreign currency purchases.
