  Results are presented of a search for cosmic sources of high energy neutrinos
with the ANTARES neutrino telescope. The data were collected during 2007 and
2008 using detector configurations containing between 5 and 12 detection lines.
The integrated live time of the analyzed data is 304 days. Muon tracks are
reconstructed using a likelihood-based algorithm. Studies of the detector
timing indicate a median angular resolution of 0.5 +/- 0.1 degrees. The
neutrino flux sensitivity is 7.5 x 10-8 ~ (E/GeV)^-2 GeV^-1 s^-1 cm^-2 for the
part of the sky that is always visible (declination < -48 degrees), which is
better than limits obtained by previous experiments. No cosmic neutrino sources
have been observed.
