Abstract
A deep exposure on the Galactic Centre region has been performed using the WFC imaging detectors on board BeppoSAX during the period 1996-98. New tran sients have been discovered and persistent source variability has been moni tored over this period. The most intriguing result is the high rate of X-ra y bursting sources implying the presence of neutron stars (NS). In fact, 13 new bursters have been detected for the first time increasing by similar t o 56% the number of this class in a region 40x40 squared degrees around the Galactic Centre.
