Abstract:	We have observed 4 VHE gamma-ray sources discovered by the High Energy Stereoscopic System (H.E.S.S.) with the Giant Metrewave Radio Telescope (GMRT). The sources viz., HESS J1813-178, HESS J1825-137, HESS J1834-087, and HESS J1837-069 were observed simultaneously at 0.61 and 0.235 GHz and at 1.28 GHz. Resolved source counterparts for 3 of these were detected at all the three frequencies. None was detected for HESS J1825-137. We investigate the consistent multiwavelength behaviour of these sources and plausible gamma-ray emission mechanisms.
