 The US Embassy in Moscow urges citizens to leave Russia immediately. The US Embassy in Moscow issued a travel advisory for its citizens due to the unpredictable consequences of the war in Ukraine, which is approaching its one-year anniversary. Do not travel to Russia due to the potential of harassment and the singling out of US citizens for detention by Russian government security officials, the arbitrary enforcement of local law, limited flights into and out of Russia, the Embassy's limited ability to assist US citizens in Russia and the possibility of terrorism, an embassy statement. It said US citizens residing or travelling in Russia should leave the country immediately and exercise increased caution due to the risk of wrongful detentions. The US government's ability to provide routine or emergency services to US citizens in Russia is severely limited, particularly in areas far from the US Embassy in Moscow, due to the Russian government limitations on travel for embassy personnel and staffing and the ongoing suspension of operations, including consular services at US consulates, he noted. The last such public warning was in September after President Vladimir Putin ordered a partial mobilization. Russian security services have arrested US citizens with spurious charges, singled out US citizens in Russia for detention and harassment, denied them fair and transparent treatment and convicted them in secret trials or without presenting credible evidence, the Embassy said. Russian authorities arbitrarily enforced local laws against US citizens' religious workers and have opened questionable criminal investigations against US citizens engaged in religious activity. Russia has opened a criminal case against a United States citizen on suspicion of espionage, the Federal Security Service said in January.
