  A number of signals involving charged cosmic rays and high-energy photons
have been interpreted as being due to annihilating dark matter. This article
provides an overview of the experimental evidence and discusses in particular
detections of antiprotons and positrons in the cosmic radiation, the diffuse
gamma-ray emission between 10 MeV and 100 GeV from the Milky Way, and the 511
keV annihilation radiation and the flux of very high-energy photons (>100 GeV)
from the Galactic Centre.
