Warped AdS$_3$ solutions in 10 dimensional supergravity that preserve ${\cal N}=(1,1)$ supersymmetry are considered. Sufficient geometric conditions for their existence, and to stop the factor experiencing an enhancement AdS$_4$, presented. The internal space of such decomposes as a foliation M$_6$ over interval where supports either SU(3)- or SU(2)-structure. former case is classified terms to...
