KIEV, Ukraine (AP) -- Ukraine's acting president says he has ordered the country's armed forces on full readiness and increased security at nuclear power plants, airports and other strategic infrastructure.
His comments on Ukrainian TV came after Russia's parliament approved military intervention in Ukraine and Russian troops and pro-Russian units took up positions across the strategic Crimea region.
The U.S. is reviewing Russia's military moves in Ukraine and trying to figure out how to respond. There was a high-level meeting at the White House today after Russia's parliament gave President Vladimir Putin the military go-ahead to deploy troops to protect Russian interests in neighboring Ukraine.
Participants in the meeting included Defense Secretary Chuck Hagel, CIA Director John Brennan, Joint Chiefs of Staff Chairman Gen. Martin Dempsey and Director of National Intelligence James Clapper.
