Carl Bildt, former Prime Minister and Foreign Minister of Sweden, shares his view from Europe:

What's going on with Russia and Ukraine?

Well, the Russians are mobilizing quite substantial military forces and transporting them, deploying them along the borders with Ukraine and in Crimea. At the same time, they are stepping up the propaganda warfare against Ukraine and undertaking also information warfare measures. What is this going to lead to? Are they prepared for some sort of direct military action of limited or larger nature? We simply don't know. But it's clearly a situation that is worrying and that we need to watch very carefully indeed.
