We present the results from the analysis of the broad-band X-ray spectra of 5Anomalous X-ray Pulsars (AXPs) and Soft $\gamma$-ray Repeaters (SGRs). We fittheir Suzaku and INTEGRAL spectra with models appropriate for the X-rayemission from the accretion flow onto a pulsar. We find that their X-rayspectra can be well described with this model. In particular we find that: (a)the radius of the accretion column is $\sim150-350$ m resulting in a transverseoptical depth of $\sim 1$; (b) the vertical Thompson optical depth is $\approx50-400$, and (c) their luminosity translates in accretion rates$\approx10^{15}\rm{g\, s^{-1}}$. These results are in good agreement with thepredictions from the fall-back disk model, providing further support in theinterpretation of AXPs and SGRs as accreting pulsars.
