We study supergravity solutions representing D3-branes with transverse 6-space having RxS{sup 2}xS{sup 3} topology. We consider regular and fractional D3-branes on a natural one-parameter extension of the standard Calabi-Yau metrics on singular and resolved conifolds. After imposing a Z{sub 2} identification on an angular coordinate these generalized ''6D conifolds'' are nonsingular spaces. The back reaction of D3-branes creates a curvature singularity that coincides with a horizon. In the presence of fractional D3-branes the solutions are similar to the original ones by Klebanov and Tseytlin and Pando Zayas and Tseytlin: the metric has a naked repulson-type singularity located behind the radius where the 5-form flux vanishes. The semiclassical behavior of the Wilson loop suggests that the corresponding gauge theory duals are confining.
