DoD Travel Warning to Eastern Ukraine... ;)
The Department of State warns U.S. citizens of the risks of travel to eastern Ukraine due to ongoing violent clashes between Russia-backed separatists and Ukrainian forces in the eastern regions of Donetsk and Luhansk. In addition, Russian military forces continue to occupy the Crimean Peninsula and are present on the eastern border of Ukraine. This supersedes the Travel Warning for Ukraine dated June 5 to provide updated information on the security situation in southern and eastern Ukraine.
