| Abstract | — We review the results on Gamma-ray Bursts obtained during the first two and a half years of operations of the INTEGRAL Burst Alert System (IBAS). In many cases GRB coordinates have been distributed with an unprecedented combination of accuracy (3 ′) and speed (20-30 s). The resulting rapid follow-ups at other wavelengths, including sensitive XMM-Newton and Swift observations, have led to several interesting results. has been designed as a general purpose mission dedicated to high-resolution imaging and spectroscopy in the hard X–ray / soft γ-ray energy range. Thanks to the good imaging capabilities of its IBIS instrument [63] and the continuous data transmission to the ground, it has been possible to set up an automatic system for the rapid distribution of GRB coordinates. In the last two and a half years, the INTEGRAL Burst Alert Systems (IBAS, [44]) has provided some of the fastest and most accurate localizations ever obtained for GRBs. In some cases the GRB coordinates were distributed while the gamma-ray emission was still ongoing. Whenever a rapid follow up at X–ray wavelengths has been carried out, mostly with XMM-Newton, an afterglow has been detected, often leading to very interesting results. After a brief description of the IBAS system, we summarize the global properties of the 28 GRBs localized to date (May 2005) and discuss a few of the most interesting cases. 2. – The INTEGRAL Burst Alert System Thanks to its 72 hours-long and highly eccentric orbit, the INTEGRAL satellite is in continuous contact with the ground stations during the observations.
