The U.S. State Department warned Americans Friday to avoid traveling to eastern Ukraine, in response to the ongoing conflict between Ukraine’s armed forces and Russia-backed separatists.
“The situation in Ukraine is unpredictable and could change quickly,” the statement said. “U.S. citizens throughout Ukraine should avoid large crowds and be prepared to remain indoors and shelter in place for extended periods of time should clashes occur in their vicinity.”
The announcement identified the eastern regions of Donetsk and Luhansk, which have been plagued with violent outbreaks for months, as the key areas to avoid. U.S. citizens have been threatened and detained in the region, according to the release. It also advised Americans to “defer all travel to the Crimean Peninsula.”
The U.S. announcement comes as the conflict in Ukraine continues to escalate with each passing day. Up to 1,ooo Russian troops appeared to enter Ukraine on Friday, and the Ukrainian government responded by instituting a mandatory conscription.
