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 deg. The neutrino flux sensitivity is 7.5 10^-8(E/ GeV)^-2 GeV^-1 s^-1 cm^-2 for the part of the sky that is always visible, which is better than limits obtained by previous experiments. No cosmic neutrino sources have been observed.
