Di-jet correlations in nucleus-nucleus collisions are studied within the hadron-string-dynamics (HSD) transport approach taking into account the reaction of the medium on the jet energy loss nonperturbatively. A comparison with the STAR and PHENIX data in central Au+Au collisions at the Relativistic Heavy Ion Collider energy {radical}(s)=200 GeV is performed differentially (i.e., with respect to correlations in azimuthal angle {Delta}{phi} and pseudorapidity {Delta}{eta}). The HSD results do not show enough suppression for the 'away-side' jets in accordance with earlier perturbative studies. Furthermore, the 'Mach-cone' structure for the angle distribution in the away-side jet as well as 'ridge' long-range rapidity correlations in the 'near-side' jet - observed by the STAR, PHENIX, and PHOBOS Collaborations - are not seen in the HSD results, thus suggesting a partonic origin.
