My friend in Ukraine gave me an update overnight:
It's not the opposition that has taken over president's residence; [Yanukovich] has abandoned it, and it was available for public to see. The Maidan guys are actually guarding it so it does not get burnt down.
The Opposition is not "controlling" the city. We have a fully-legitimate parliament that is working, and yes, patrols from Maidan are around to prevent crime as thousands of "titushkies" (thugs) are in Kiev, paid by the government.
Another very important point: the opposition for us is basically three guys who have their own political agenda. When it was starting peacefully back in November, they had their political rallies next door to Maidan, which is the main place. Soon they agreed to join efforts if they each of them stopped individually using the "Maidan," as the place represents every party. The protests were first for EU, and then changed into anti-Yanukovich issues once students's blood was shed in November. So our "opposition" is not the driving force. It's a bit of a façade. But they're not the power, and they get kicked by Maidan, too.
But the guys who were the majority of the Parliament, the Party of Regions, are gradually leaving the party. So there is no one "controlling" the parliament. They are simply scared for their future, so they change colors, and they vote vote vote with the majority.
The capital is quieter today, and Russia, preoccupied with the closing ceremonies in Sochi, haven't turned their attention back to their old province. That, I expect, will happen tomorrow.
