      Gamma-Ray Bursts (GRBs) are among the most luminous transients in our universe. Due to the large amounts of energy they release, they have long been discussed as potential sources of Ultra-High-Energy Cosmic Rays (UHECR) - which however is challenged by the absence of neutrino detections in coincidence with GRBs. At the same time, the exact production mechanism of the prompt gamma-ray emission is still under debate. Focussing on the prompt phase, I will briefly review the current status of theoretical models, emphasizing especially the multi-messenger connection.

      High-energy neutrinos were discovered by the IceCube Neutrino Observatory in 2013, but their origin remains an unsolved mystery. I will present the latest results on the search for neutrino sources, which suggest that some neutrinos are produced by so-called “tidal disruption events”, the process by which stars are shredded when passing close to supermassive black holes.
