We present observational evidence supporting a picture where the -ray source 2EGS J1703-6302 is the result of the interaction between cosmic rays (CRs) accelerated in a supernova remnant (SNR) and a nearby HI cloud. The SNR has been disclosed by filtering the diffuse disk emission from new 1.42 GHz continuum observations of the radio field around 2EGS J1703-6302. The cloud was detected through neutral hydrogen line observations of the same area of the sky. The CR enhancement in the SNR with respect to the local value is about a factor .
