  Arrival directions of 40 neutrino events with energies >~100 TeV, observed by
the IceCube experiment, are studied. Their distribution in the Galactic
latitude and in the angular distance to the Galactic Center allow to search for
the Milky-Way disk and halo-related components, respectively. No statistically
significant evidence for the disk component is found, though even 100% disk
origin of the flux is allowed at the 90% confidence level. Contrary, the
Galactic Center-Anticenter dipole anisotropy, specific for dark-matter decays
(annihilation) or for interactions of cosmic rays with the extended halo of
circumgalactic gas, is clearly favoured over the isotropic distribution (the
probability of a fluctuation of the isotropic signal is ~2%).
