A new classified intelligence assessment concludes it is more likely than previously thought that Russian forces will enter eastern Ukraine, CNN has learned.
Two administration officials described the assessment but declined to be identified due to the sensitive nature of the information.
The officials emphasized that nothing is certain, but there have been several worrying signs in the past three to four days.
“This has shifted our thinking that the likelihood of a further Russian incursion is more probable than it was previously thought to be,” one official said.
The buildup is seen to be reminiscent of Moscow’s military moves before it went into Chechnya and Georgia in both numbers of units and their capabilities.
U.S. military and intelligence officials have briefed Congress on the assessment.
As a result, Republican members of the House Armed Services Committee late Wednesday sent a classified letter to the White House expressing concern about unfolding developments.
An unclassified version obtained by CNN said committee members feel “urgency and alarm, based on new information in the committee’s possession.”
The committee said there was “deep apprehension that Moscow may invade eastern and southern Ukraine, pressing west to Transdniestria and also seek land grabs in the Baltics.”
