BeppoSAX has detected so-far 14 GRB in the field of view of Wide Field Cameras following gamma-ray triggers. We pointed the direction of 12 of them with Narrow Field Instruments. In almost all cases we detected X-ray sources that, in the large majority we associate with the GRB, due to their temporal behaviour. For a large fraction of these GRBs, transient sources in other wavelengths and host galaxies have been detected. The main spectral and temporal features of these afterglow sources, their energetics and the association with other features are reviewed.

Key words: gamma-rays: bursts -- instrumentation: detectors
