We construct a family of supersymmetric solutions in Type IIB supergravity of the form \rm WAdS3× \rm WS3× T4, where \rm WAdS3 and \rm WS3 denote a warped anti-de Sitter spacetime and a warped 3-sphere, respectively, while T4 denotes an internal 4-torus. These backgrounds are constructed by uplifting corresponding solutions in the D=6, N=(1,1) ungauged supergravity resulting from the compactification of Type IIB supergravity on a T4/ℤ2-orientifold. More specifically, the supersymmetric solutions are \rm WAdS3× \rm WS3× T4 with lightlike warped AdS3 and \rm WAdS3× \rm S3× T4 in which the warping of AdS3 is generic. Moreover, we also construct solutions in the form of a warped product LM3ζ,ω×\rm w S3× T4 of a 2-parameter deformation LM3ζ,ω of \rm AdS3 and a three-sphere. We discuss the relation of these backgrounds to known solutions.
