We present new exact three-dimensional black-string backgrounds, whichcontain both NS--NS and electromagnetic fields, and generalize the BTZ blackholes and the black string studied by Horne and Horowitz. They are obtained asdeformations of the Sl(2,R) WZW model. Black holes resulting from purelycontinuous deformations possess true curvature singularities. When discreteidentifications are introduced, extra chronological singularities appear, whichunder certain circumstances turn out to be naked. The backgrounds at handappear in the moduli space of the Sl(2,R) WZW model. Hence, they provide exactstring backgrounds and allow for a more algebraical CFT description. This makespossible the determination of the spectrum of primaries.Comment: JHEP style, 33 pages, 1 figur
