  Gamma-ray studies are an essential tool in our search for the origin of
cosmic rays. Instruments like the Fermi-LAT, H.E.S.S., MAGIC and VERITAS have
revolutionized our understanding of the high energy Universe. This paper
describes the status of the very rich field of gamma-ray astrophysics that
contains a wealth of data on Galactic and extragalactic particle accelerators.
It is the write-up of a rapporteur talk given at the 32nd ICRC in Beijing,
China in which new results were presented with an emphasis on the cosmic-ray
related studies of the Universe.
