  We have observed a sample of 64 small diameter sources towards the central -6
degree < l< 6 degree, -2 degree < b < 2 degree of the Galaxy with the aim of
studying the Faraday rotation measure near the Galactic Centre (GC) region. All
the sources were observed at 6 and 3.6 cm wavelengths using the ATCA and the
VLA. Fifty nine of these sources are inferred to be extragalactic. The
observations presented here constitute the first systematic study of the radio
polarisation properties of the background sources towards this direction and
increases the number of known extragalactic radio sources in this part of the
sky by almost an order of magnitude. Based on the morphology, spectral indices
and lack of polarised emission, we identify four Galactic HII regions in the
sample.
