COOPER: And welcome back to our continuing coverage of the aftermath of the Paris terror attacks. I'm here in the Plaza de la Republique. You're looking there at a live shot of the G20 Summit where President Barack Obama is expected to speak momentarily. France's Francois Hollande is also expected to speak, a joint address to the parliament. Here, I'm joined by Christiane Amanpour. A lot of focus first of all from France's president. This is a historic address, very rare for him to speak, both houses of parliament and in an address to the nation at the same time.</s>CHRISTIANE AMANPOUR, CNN CHIEF INTERNATIONAL CORRESPONDENT: I think Versailles it's the first time or very rare, since 1848, apparently. But we expect, according to French politicians who will be there, that he will reiterate the message that he has been talking about, which is France is at war. A war has been declared upon us. And we have to, as they've said, every French official, we have to destroy this enemy. And we really want to see what the world leaders have decided in Turkey in terms of eradicating this threat, because war has been declared on our cities now.</s>COOPER: Let's go to Michelle Kosinski who is there in Turkey as we await President Obama. We now believe President Obama will be speaking before France's president. Michelle, what are you hearing today?</s>MICHELLE KOSINSKI, CNN CORRESPONDENT: We should hear from the president any minute --</s>COOPER: And the president has just stepped out, so let's listen in. Yes, Michelle, the president's on the stage. Let's listen.</s>BARACK OBAMA, PRESIDENT OF THE UNITED STATES: -- President Erdogan and Turkey for outstanding work in hosting this G20 Summit.
