  We present the results of three dimensional relativistic hydrodynamic
simulations of interaction of AGN jets with a dense turbulent two-phase
interstellar medium, which would be typical of high redshift galaxies. We
describe the effect of the jet on the evolution of the density of the turbulent
ISM. The jet driven energy bubble affects the gas to distances up to several
kiloparsecs from the injection region. The shocks resulting from such
interactions create a multi-phase ISM and radial outflows. One of the striking
result of this work is that low power jets (P_jet < 10^{43} erg/s) although
less efficient in accelerating clouds, are trapped in the ISM for a longer time
and hence affect the ISM over a larger volume. Jets of higher power drill
through with relative ease. Although the relativistic jets launch strong
outflows, there is little net mass ejection to very large distances, supporting
a galactic fountain scenario for local feedback.
