Abstract. Neutrinos constitute a unique probe since they escape from their sources, travel undisturbed on cosmological
distances and are produced in high-energy (HE) hadronic processes. In particular they would allow a direct
detection and unambiguous identification of the acceleration sites of HE baryonic cosmic rays (CR), which
remain unknown. The latest results achieved with the current experiments are briefly reviewed, including
the efforts towards a multi-messenger approach.
