WATCH: State Department estimates 6,600 U.S. citizens are living in Ukraine

Last fall, the U.S. State Department estimated that approximately 6,600 U.S. citizens were living in Ukraine. It also estimated the number of U.S. tourists and short term visitors to be approximately 16,000.

“While we estimated at the time there could be 16,000 tourists and visitors, our best assessment is that that number is much, much lower now,” said State Department Spokesman Ned Price.

“We do not believe this figure to be an accurate reflection of where we are now,” he said.

Price said although the State Department has been suggesting that Americans in Ukraine “strongly consider” departing the country, he says that may be a difficult decision for many.

“Many of these individuals are likely to be dual U.S.-Ukrainian citizens, many of whom I consider Ukraine to be to be home,” he said.

Price also said the sharp debate between the U.S. and Russia regarding Ukraine in the U.N. Security Council was “important.”

“We thought it was important that they do so in that venue, and with that level of exposition, so that the world could hear it and the Russian Federation could hear it,” he said.

Russia accused the West on Monday of “whipping up tensions” over Ukraine and said the U.S. had brought “pure Nazis” to power in Kyiv.

U.S. Ambassador Linda Thomas-Greenfield shot back that Russia’s growing military force of more than 100,000 troops along Ukraine’s borders was “the largest mobilization” in Europe in decades, adding that there has been a spike in cyberattacks and Russian disinformation

It was the first open session where all protagonists in the Ukraine crisis spoke publicly, even though the U.N.’s most powerful body took no action.
