Then, fight night in Vegas.

AMANPOUR: Good morning. Lots to get to today. But first, some news since your morning papers.
Breaking news to report: A powerful 7.2 earthquake has rocked Turkey, with its epicenter near the city of Van. A local mayor reports, there are so many dead, several buildings have collapsed. There is too much destruction, he says. Rescue workers are struggling to reach victims trapped under the rubble.
And a milestone in the Middle East this morning, the first election of the Arab Spring. The uprising began in Tunisia last December when a fruit vendor set himself on fire in protest of an oppressive regime. Today, Tunisians headed to the polls. There were 11,000 candidates from 80 political parties, and results will be announced tomorrow.
And in Libya, a day of jubilation as leaders formally declare the country liberated. The clock now starts for a constitutional assembly within eight months and parliamentary and presidential elections within a year.
Meantime, an official autopsy report confirms Moammar Gadhafi was killed by a shot to the head. The transition government has been under international pressure to explain the circumstances of Gadhafi's death. And Secretary of State Hillary Clinton is in the region. I spoke with her about the changes in Libya and the administration's decision to pull all American troops from Iraq.
AMANPOUR: Madam Secretary, thank you for joining us.
Are you in Herman Cain's famously designated "Beki-beki-beki-bekistan"?
CLINTON: Well, you know, there's a zero-zero-zero change I'm going to comment on Republican politics, but I am in Uzbekistan.
AMANPOUR: Let me turn to something more serious. You were actually in Libya earlier this week. And this week, we all saw the video of the bloodied and dazed Moammar Gadhafi. We saw him now lying in a freezer while Libyans take a look at him. What was your reaction to that video, your gut reaction?
