While Korn are currently on a tour of Russia, they've had to postpone their upcoming on May 16 in Kiev because it is not safe in the slightest for them to go there right now. That's what the State Department is warning them about, and I've heard they know a thing or two about keeping people safe. According to the band's website:
"As The State Department of United States of America has recently issued a travel advisory warning against any non-essential travel to Kiev, both Korn and the promoter have decided it would be in the best interest of the fans that the show scheduled for May 16, 2014 be postponed to a later date. Full ticket refunds will be available immediately from point of purchase. All of Korn's other dates on their tour of Russia will continue as planned."
World news buffs are aware that there is major unrest in the Ukraine right now, as Russia has taken over the Crimean peninsula leading to a nasty back and forth between the two countries.
