We present experimental evidence of a breakdown of localization at low temperatures in strongly interacting two-dimensional electrons systems with moderate background disorder. The observation is manifested by a transition from an activated transport behavior at high temperature to a metal-like (dp/dT>0) behavior at low temperature T less than or similar to 1 K. The results have been achieved in mesoscopic two-dimensional electron systems (2DES), where the disorder strength was systematically
