Gamma Ray Bursts (GRBs) have been proposed as one {\it possible} class of sources of the Ultrahigh Energy Cosmic Ray (UHECR) events observed up to energies $\gsim10^{20}\ev$. The synchrotron radiation of the highest energy protons accelerated within the GRB source should produce gamma rays up to TeV energies. Here we briefly discuss the implications on the energetics of the GRB from the point of view of the detectability of the prompt TeV gamma rays of proton-synchrotron origin in GRBs in the up-coming ICECUBE muon detector in the south pole. : 3 pages Latex including 1 ps figure, invited parallel session talk given at the IXth International Symposium on Particles, Strings and Cosmology (PASCOS-03), TIFR, Mumbai, India, Jan 2003, to appear in the proceedings to be published as a special issue of Pramana -- Jour. of Physics, style files included
