KYIV, Jan 12 - The U.S. State Department has included Ukraine in the second group of countries out of four in terms of level of security for U.S. citizens – the countries in which they should exercise increased caution.

"Exercise increased caution in Ukraine due to crime and civil unrest. Some areas have increased risk," reads a travel advisory posted on the website of the Department of State.

In particular, it is recommended not to visit Crimea and eastern parts of Donetsk and Luhansk regions.
