Abstract: 

After a brief review of the phenomenology of gamma-ray burst sources, 
I discuss the theoretical ideas used to interpret them, and in 
particular the fireball shock scenario and its implications for the 
MeV emission and the X-ray, optical and radio afterglows. I then 
describe the prospects for GeV-TeV photon detections, and for 
GeV-PeV neutrino detection.
