  A search for cosmic neutrino point-like sources using the ANTARES and IceCube
neutrino telescopes over the Southern Hemisphere is presented. The ANTARES data
was collected between January 2007 and December 2012, whereas the IceCube data
ranges from April 2008 to May 2011. Clusters of muon neutrinos over the
diffusely distributed background have been looked for by means of an unbinned
maximum likelihood maximisation. This method is used to search for a localised
excess of events over the whole Southern Sky assuming an $E^{-2}$ source
spectrum. A search over a pre-selected list of candidate sources has also been
carried out for different source assumptions: spectral indices of 2.0 and 2.5,
and energy cutoffs of 1 PeV, 300 TeV and 100 TeV. No significant excess over
the expected background has been found, and upper limits for the candidate
sources are presented compared to the individual experiments.
