Russian President Vladimir Putin says his forces could take control of Ukraine's capital city in just two weeks if given the order.
This, according to the outgoing President of the European Commission, Jose Manuel Barroso, who says Putin made the statement to him in a private phone conversation.
The Kremlin has not denied that Putin made the remark, but said it WAS taken out of context.
They've threatened to release an audio recording and transcript of the phone conversation to clarify what Putin said, and slammed Barroso for making it public in the first place.
Barroso claims Putin told him that Kiev would be an EASY conquest for his forces.
World leaders are starting to arrive in Wales for a NATO summit on Thursday, where the crisis in Ukraine will dominate talks.
NATO has proposed setting up a rapid response force to deter threats to Eastern European member states, and will decide whether to deploy it to Baltic states, who remain worried about Russian aggression.
U.S. President Barack Obama arrived in one of those states, Estonia, on Wednesday, to allay concerns before heading to the NATO summit in Wales.
