The X-ray and radio flares observed in X-ray binaries and active galactic nuclei are attributed to energetic electrons in the plasma ejecta from the accretion flows near the black hole in these systems. It is argued that magnetic reconnection could occur in the coronae above the accretion disc aroun...
