We present a multiwavelength study of the environment of the unidentified
X-ray/gamma-ray sources IGR J18027-1455 and IGR J21247+5058, recently
discovered by the IBIS/ISGRI instrument, onboard the INTEGRAL satellite. The
main properties of the sources found inside their position error circles, give
us clues about the nature of these high-energy sources.Comment: 8 pages, 4 figures, Proceedings of the Conference "The
