Putin dances at Austrian minister's wedding, setting off alarm bells across Europe

As Russian President Vladimir Putin danced arm in arm with Kneissl at a vineyard in south Austria on Saturday, many were left wondering what Putin's "private visit" could portend for the countries' growing public relationship.

Putin arrived to the wedding carrying a bouquet of flowers, and accompanied by a troupe of Cossack singers to serenade the newlyweds, on a stopover on his way to meet German Chancellor Angela Merkel outside Berlin.
