Star forming regions in the southern sky are relatively less studied compared to their northern counterparts. In this context, I will present the results of our multi-wavelength analysis towards few southern molecular clouds, with specific emphasis on IRAS 17256-3631. Our analysis of the star forming activity of these regions cover a wide-wavelength range, from near-infrared to radio. While the embedded cluster and warm dust components are examined using infrared wavelength bands, the radio continuum has been used to probe the ionised gas. We have also mapped the low frequency radio recombination line (RRL) emission using GMRT, India, and we explain the observed continuum morphology using the kinematics of RRLs. From our analysis, we find objects in different evolutionary stages, from quiescent cores to evolved star clusters. The results reveal that an interplay of various feedback mechanisms and cloud density structure govern the observed morphologies, kinematics and star formation activity in these regions.
