  We analyze publicly available Fermi-LAT high-energy gamma-ray data and
confirm the existence of clear spectral feature peaked at E=130GeV. Scanning
over the Galaxy we identify several disconnected regions where the observed
excess originates from. Our best optimized fit is obtained for the central
region of Galaxy with a clear peak at 130GeV with local statistical
significance 4.5 sigma. The observed excess is not correlated with Fermi
bubbles. We compute the photon spectra induced by dark matter annihilations
into two and four standard model particles, the latter via two light
intermediate states, and fit the spectra with data. Since our fits indicate
sharper and higher signal peak than in the previous works, data favors dark
matter direct two-body annihilation channels into photons or other channels
giving only line-like spectra. If Einasto halo profile correctly predicts the
central cusp of Galaxy, dark matter annihilation cross-section to two photons
is of order ten percent of the standard thermal freeze-out cross-section. The
large dark matter two-body annihilation cross-section to photons may signal a
new resonance that should be searched for at the CERN LHC experiments.
