It was a shooting in Simferopol. I'd give you a link but I'd rather you look it up yourself and decide which source you want to believe. But a search will yield several results. They all say more or less the same thing. Russian troops stormed a Ukrainian military base and the Ukrainians fired back in self-defense. One killed on both sides (though I have seen Ukrainian casualties listed as two in some places) and several people were wounded. Some Ukrainian soldiers were captured as well, including a Colonel who I believe has since defected to the Russian side.
