Attack on American airmen in Frankfurt: A gunman, reported by the U.K.’s Guardian as believed to be from Kosovo, opened fire on a military bus at the Frankfurt airport, killing two U.S. airmen and badly wounding two others. While no potential motive has been ascribed, the German authorities arrested a suspect inside the airport shortly after the attack, who they’ve identified as Arif Uka, a twenty-one year old. The Pentagon has not yet offered comment. source
