  We compute the proton-proton multiplicity distributions at LHC energies in
the framework of a multiple scattering model assuming a Poisson distribution
for each inelastic collision. Multiple scattering is essential to broaden the
multiplicity distribution. We obtain approximate KNO scaling for small
pseudo-rapidity intervals ($|\eta | < 0.5$) and sizable KNO scaling violations
for larger ones, in agreement with experiment.
