N2 - We discuss, in the context of the strongly-coupled E8 × E8 heterotic string proposed by Hořava and Witten, the appearance of anomalous U(1)x symmetries of a nonperturbative origin, related to the presence, after compactification, of five-branes in the five-dimensional bulk of the theory. We compute the gauge anomalies and the induced Fayet-Iliopoulos terms on each boundary, which we find to be lower than the universal one induced in the weakly coupled case.
