Using Monte Carlo simulations, we demonstrate photopion production fromFermi-accelerated protons and the resulting neutrino production in gamma-raybursts. Unless internal shocks occur at quite large distance from the center,ultra high-energy protons are depleted by photopion production and synchrotronradiation. Internal shocks at fiducial distance cause neutrino bursts, whichaccompany gamma-ray bursts originating from electromagnetic cascades.Comment: 20 pages, 9 figures, accepted for publication in ApJ 624, #
