%X Most γ-ray detected active galactic nuclei are blazars with one of their relativistic jets pointing towards the Earth. Only a few objects belong to theclass of radio galaxies or misaligned blazars. Here, we investigate the nature of the object PKS 0625−354, its γ-ray flux and spectral variabilityand its broad-band spectral emission with observations from H.E.S.S., Fermi-LAT, Swift-XRT, and UVOT taken in November 2018. The H.E.S.S.light curve above 200 GeV shows an outburst in the first night of observations followed by a declining flux with a halving time scale of 5.9 h. Theγγ-opacity constrains the upper limit of the angle between the jet and the line of sight to ∼10◦. The broad-band spectral energy distribution showstwo humps and can be well fitted with a single-zone synchrotron self Compton emission model. We conclude that PKS 0625−354, as an objectshowing clear features of both blazars and radio galaxies, can be classified as an intermediate active galactic nuclei. Multi-wavelength studiesof such intermediate objects exhibiting features of both blazars and radio galaxies are sparse but crucial for the understanding of the broad-bandemission of γ-ray detected active galactic nuclei in general
