In late January, the President offered a package of concessions under which Yatsenyuk, the opposition leader, would have become the prime minister and, under the President's offer, been able to dismiss the government. He also offered Klitschko the post of deputy prime minister on humanitarian issues. He also agreed to a working group looking at changes to the constitution. But the opposition refused.
12. Why did the opposition pass on the offer?
The concessions weren't enough to satisfy them. They said Yanukovych had hardly loosened his grip on the government, nor had he seemingly reined in authorities' approach to protesters. "We're finishing what we started," Yatsenyuk said.
13. But over the weekend, it seemed things were getting better, weren't they?
Yes. On Sunday, protesters vacated Kiev's City Hall, unblocked a major street and left other government buildings in exchange for the government dropping charges against those arrested. But any breakthrough was a distant memory by Tuesday.
14. Why? What happened Tuesday?
The opposition wanted to introduce amendments in parliament that would have limited the President's powers and restored the constitution to what it was in 2004. But the speaker of parliament refused to allow it. Bloody clashes followed.
15. Who was to blame for the clashes?
Depends on whom you ask. The government pointed the finger at protesters. The opposition, in turn, blamed the government. Regardless, it was the bloodiest day of protests up to that point; 28 people died.
16. Wasn't there a truce called?
Yes, the government and opposition agreed on a truce late Wednesday. But it barely took hold -- and blood was flowing again Thursday.
17. What caused the fresh clashes?
Gunfire erupted Thursday at Maidan, or Independence Square, which has been ground zero for anti-government protesters. At least 20 people died. It's unclear what prompted the gunfire. Again, finger-pointing followed: The government said protesters broke the truce; the protesters said the government did.
18. So, what happens next?
Top international diplomats have been trying to resolve the crisis. There's also been talk of sanctions.
19. Will sanctions help?
Analysts warn there's little that outside pressure could do, especially if the Ukrainian military gets involved on the side of the government.
20. What's the takeaway here?
Street protests that started in November over a trade pact have swelled into something much bigger -- a demand that the President loosen his grip on power and the constitution be changed. As a result, the eastern European country is in the midst of a wave of anti-government protests, the likes of which it hasn't seen in 10 years.
There's something else: Ukraine, the biggest frontier nation separating Russia and the European Union, is something of a pawn between Russia and the West. The EU and the U.S. think Russia wields a lot of influence. Russia denies it.
One open-ended question is how much worse it will all get.
"My own hunch," said Richard Haass, president of the Council on Foreign Relations, "is this is going to continue to escalate."
