President Obama blamed Russia for the violence in Ukraine and said its "incursion" into the former Soviet state will only carry additional costs.

"Russia has deliberately and repeatedly violated the sovereignty and territorial integrity of Ukraine, and the new images of Russian forces inside Ukraine make that plain for the world to see," Obama said at a White House news conference on Thursday.

Russia is allowing former NSA contractor Edward Snowden to remain in the country for at least three more years.

Speaking to reporters in Moscow on Thursday, attorney Anatoly Kucherena said Snowden's application had been approved Aug. 1.

If you remember, Snowden has been in exile for a little more than a year. He fled the United States when he decided to leak a cache of classified documents that revealed some of the United States' most deeply held security secrets.

U.S. Accuses Russia Of Violating Nuclear Treaty

Jul 29, 2014

The Obama administration says Russia has violated a 1987 nuclear pact by testing a ground-launched cruise missile.

An administration official called the matter "very serious" and says the U.S. is "prepared to discuss this in a senior-level bilateral dialogue immediately." The New York Times reports that President Obama notified Russian President Vladimir Putin of the finding in a letter Monday.

Both pro-Russian rebels and the Ukrainian government forces are denying any responsibility for downing the Malaysia Airlines jetliner carrying 295 passengers and crew. Multiple reports state the Boeing 777, traveling from Amsterdam to Kuala Lumpur, appeared to have broken up before impact, with the burning wreckage scattered over a wide area. All passengers are believed to have died. 

At a press event in Delaware, President Obama said he has directed national security advisors to stay close contact with the Ukrainian government. Reuters reports that just yesterday, the U.S. administration tightened its sanctions against Russia over the ongoing fighting in Ukraine. Shortly thereafter, Ukraine claimed that Russian had downed one of its war planes.

U.S. troops began joint military exercises in Poland this week, in response to Russia's continued incursion into Ukraine.  The Pentagon says troops will also be deployed to Lithuania, Latvia and Estonia.

Vice President Joe Biden arrived in Kiev on Monday as a show of support for the pro-Western Ukrainian government. As he met with the nation's leaders he called on Russia to "stop talking and start acting" to defuse the crisis.

So far, that doesn't seem to be happening. 

There will be few days that better symbolize the crisis in Ukraine.

On Friday:

As Ukrainian Prime Minister Arseniy Yatsenyuk was signing an agreement on closer relations with the European Union ...

... Russian President Vladimir Putin was signing the laws his country has put in place to take Crimea from Ukraine and make it part of the Russian Federation.

Russia's parliament has unanimously approved a request by President Vladimir Putin to authorize the intervention of Moscow's forces in Ukraine until "the normalization of the political situation" there. In response, Ukraine put its own forces on alert and warned that a Russian invasion would spark war between the two countries.

The remaining members of the punk rock band Pussy Riot have been released from prison in Russia, a few months short of serving their full two-year sentences for "hooliganism" — a charge that the band's supporters say was just a trumped-up effort to quash free speech.

Scientists from Colombia believe they have pinpointed the origin of the giant meteor that smashed into a remote region of Russia earlier this month, injuring more than 1,000 people.

A Russian judge today found three members of the punk rock band Pussy Riot guilty of hooliganism connected to "religious hatred."

Word of the verdict came just before 7:30 a.m ET. Just before 10 a.m. ET, the judge announced that each woman was sentenced to serve two years in jail — the minimum that could be imposed.
