Recent H.E.S.S. results on extra-galactic sources
  Since the beginning of scientific operations in 2003, more than 20
extra-galactic sources have been detected with H.E.S.S. (High Energy
Stereoscopic System) at very high energies (VHE): apart from the starburst
galaxy NGC 253, all of them are active galactic nuclei (AGNs). BL Lac objects
are by far the dominant AGN sub-class in the H.E.S.S. extra-galactic sky, but
two radio-galaxies and one flat-spectrum radio quasar (FSRQ) have been detected
as well. The study of extra-galactic VHE emitters will be improved in the near
future by the completion of a fifth 24m-diameter telescope (H.E.S.S. II). In
this talk, a review of the AGNs seen by H.E.S.S. will be given, including the
latest results achieved, namely the detection of VHE emission from the blazars
1RXS J101015.9-311909, SHBL J001355.9-185406, 1ES 1312-423, AP Lib and the BL
Lac candidate HESS J1943+213.
