In an attempt to increase the number of known microquasars, we have carried out a search for new Radio Emitting X-ray Binaries (REXBs). To this end, we have performed a cross-identification between the X-ray ROSAT all sky survey Bright Source Catalog (RBSC) and the radio NRAO VLA Sky Survey (NVSS) catalogs under very restrictive selection criteria for sources with |b| < 5°, and obtained a sample of 13 radio-emitting X-ray sources. Follow-up observations of 6 of these sources with the VLA have provided accurate coordinates, that have been used to discover optical counterparts for all of them. We have observed these six sources with the EVN and MERLIN at 5 GHz. Five of the six observed objects have been detected and imaged, presenting different morphologies: one source with a two-sided jet, three sources having a one-sided jet and a compact source. With all the available information up to now, we conclude that two of the sources are promising microquasar candidates in our Galaxy.
