We present a multiwavelength study of the environment of the unidentifiedX-ray/gamma-ray sources IGR J18027-1455 and IGR J21247+5058, recentlydiscovered by the IBIS/ISGRI instrument, onboard the INTEGRAL satellite. Themain properties of the sources found inside their position error circles, giveus clues about the nature of these high-energy sources.Comment: 8 pages, 4 figures, Proceedings of the Conference "The  Multiwavelength Approach to Unidentified Sources", to appear in the journal  Astrophysics and Space Scienc
