Thanks to follow-up observations performed with the X-ray telescope (XRT) on board Swift sev-eral new unidentified hard X-ray sources revealed by INTEGRAL heve been localized with a po-sitional accuracy of few arcseconds, thus allowing a more efficient and reliable search for optical, UV, infrared and radio counterparts. Here we provide spectral information over a broad range of frequencies for three still unclassified INTEGRAL objects: IGR J18249–3243, IGR J19443+2117 and IGR J22292+6647. Overall, their optical, UV, infrared and radio characteristics together with their X-/gamma-ray properties, point to an AGN classification for all three sources.
