We present the XMM-Newton observations of X-ray afterglows of the gamma-raybursts GRB 011211 and GRB 001025. For GRB 011211 XMM detected fading X-rayobject with an average flux in 0.2-10 keV declining from 2.7$\times10^{-13}$erg cm$^{-2}$ s$^{-1}$ during the first 5 ks of 27-ks observation to1.0$\times10^{-13}$ erg cm$^{-2}$ s$^{-1}$ toward the end of the observation.The spectrum of the afterglow can be fit to a power law withalpha=2.16$\pm$0.03 modified for the Galactic absorption. No significantevolution of spectral parameters has been detected during the observation.Similar X-ray spectrum with alpha=2.01$\pm$0.09 has been observed by the XMMfrom the GRB 001025. The non-detection of any extra absorption in these spectraabove the Galactic value is an interesting fact and may impose restrictions tothe favorable GRB models involving burst origin in star-forming regions.Finally we discuss soft X-ray lines from GRB 011211 reported by Reeves etal.(2002) and conclude that there is no definitive evidence for the presense ofthese lines in the spectrum.Comment: submitted to ApJL (7 pages, 4 figures, 2 tables, emulateapj.sty
