9. But wasn't the law repealed?
Yes, ultimately it was. Amid intense pressure, deputies loyal to Yanukovych backtracked and overturned it. But by then, the protests had become about something much bigger: constitutional reform.
10. What change in the constitution did they want to see?
The protesters want to see a change in the government's overall power structure. They feel that too much power rests with Yanukovych and not enough with parliament.
11. What did the government do?
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.
