We performed a re-analysis of all consolidated data of the INTEGRAL AO-3 Galactic Bulge monitoring program (ATel #438; Kuulkers et al. 2006, astro-ph/0603130), and detected a new source with IBIS/ISGRI, which we designate IGR J17354-3255. It was detected in two consecutive 1800 sec pointings from 21 Apr 2006 04:27 to 05:29 (UT) at RA, Dec (J2000.0) = 17h 35m 25s, -32o 55' 18", with a statistical error radius of 4' (90% confidence). The average 20-60 keV flux was about 18 mCrab during the two pointings. Unfortunately, the Jem-X instrument was off at that time. No previously known X-ray or gamma-ray emitting source is found within the error circle from the Simbad database.

The Galactic Bulge monitoring program will be continued throughout the next INTEGRAL AO-4 period (16 Aug 2006 - 15 Aug 2007), starting on 16 Aug 2006. Continuing the service to the scientific community, the near-real-time results (Jem-X and IBIS/ISGRI light curves and mosaic images) will be made publicly available as soon as possible at
