The US embassy in Moscow has urged American nationals residing in Russia to depart the country immediately, citing what it claimed to be possibility that Russia could conscript dual nationals for military service.
"Russia may refuse to acknowledge dual nationals' US citizenship, deny their access to US consular assistance, prevent their departure from Russia, and conscript dual nationals for military service," read an alert posted on the embassy's website, Xinhua news agency reported.
"US citizens should not travel to Russia and those residing or travelling in Russia should depart Russia immediately while limited commercial travel options remain," it added.
The advisory further instructs Americans residing in Russia to refrain from political or social protests and to avoid photographing security personnel at these events. It noted that "the right to peaceful assembly and freedom of expression are not guaranteed in Russia."
"Russian authorities have arrested US citizens who have participated in demonstrations," the alert added.
The advisory came roughly a week after Russia announced a partial mobilization amid the conflict with Ukraine.
Citing the severe limitations on the embassy's ability to assist US citizens, and conditions, including transportation options, Americans are advised to make independent travel arrangements at the earliest.
