XMM-Newton data analysis of the bright galaxy 4U 1344-60 is presented. The observed X-ray spectrum is complex. The continuum emission can be described as a power law obscured by two neutral absorption components. Interestingly, 4U 1344-60 exhibits a broad and skewed iron line at 6.4 keV most likely originated in a few gravitational radius from the black hole. Optical spectral analysis was also presented. On the basis of its results, we propose to classify 4U 1344-60 as a Seyfert 1.5 galaxy located at z=0.012+/-0.001.
