Your daily scoop of what State of the Union is watching today, August 28, 2014
1. Ukraine says it has been invaded by Russia. A U.S. official says as many as 1,000 Russian troops are in Ukraine to aid pro-Russian rebels. Russia denies that it has launched a military invasion or arming the separatists. In a U.N. Security Council emergency meeting on Ukraine, U.S. Ambassador Samantha Power accused Russia of lying about its actions. “Russia is not listening, instead they have come before this council to say everything but the truth,” Power said. The latest incident comes just two days after Russian President Vladimir Putin and Ukraine's President Petro Poroshenko were photographed shaking hands.
2. ISIS claims it executed 250 Syrian soldiers Wednesday. The terrorist group released a video showing the soldiers on a death march. This comes as President Obama considers expanded military action against ISIS targets. The group virtually controls the Iraq-Syria border as well as areas inside Iraq.
3. Detained U.N. peacekeepers. The United Nations says 43 of its peacekeepers are being held in the Golan Heights. An Israeli military official says the peacekeepers were taken by Al-Nusra Front, a Syrian rebel group with ties to Al Qaeda. Al-Nusra currently controls the border crossing between Syria and the Golan Heights.
4. Hillary Clinton speaks. The potential 2016 Democratic presidential candidate has made her first public comments about the recent unrest in Ferguson, Mo. At an event Thursday in San Francisco, said her "heart just broke" for Michael Brown's family. "Behind the dramatic terrible pictures on television are deep challenges that will be with them and with us long after the cameras move on," Clinton said. "This is what happens when the bonds of trust and respect that hold any community together fray. Nobody wants to see our streets look like a war zone. Not in America. We are better than that." The 18-year-old Brown was unarmed when he was shot and killed by a police officer August 9.
