We report on ROSAT and ASCA observations of the LINER NGC1052, which is the first one where broad optical lines in polarized light have been observed. The 2-10 keV spectrum is very flat, with an observed photon index (Gamma) ~0.1. A model where a nuclear source is - partly or totally - obscured by a screen of matter with column density ~10^23 atom/cm/cm is the most convincing explanation for the observed flatness. This agrees with the hypothesis that the LINERs are a population of low-luminosity AGN, to which the Seyfert unification scenario applies. The intrinsic spectral index is still rather flat (1.0-1.4), as observed in a few type-2 Seyferts so far or predicted if the accretion occurs in an advection-dominated flow.
