In the course of a systematic analysis of INTEGRAL archival data, we discovered three new hard X-ray sources, IGR J10043-8702, IGR J10500-6410 and IGR J15283-4443, detected by the IBIS/ISGRI instrument. Each source was visible only in a single pointing (about 2 ksec). The coordinates (J2000, deg), statistical error radius, 17-40 keV flux in units of mCrab, detection significance and observation time are given below.
