Two and a half years of GRB localizations with the INTEGRAL Burst Alert System

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 arcmin) 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.
