In this contribution, we present the follow-up of several recent IceCube real-time alerts of potential astrophysical neutrinos, using the complementarity of KM3NeT-ORCA and KM3NeT-ARCA data. Due to their geometry, these detectors cover a broad neutrino energy range, from few GeV to tens of PeV. At the time of each alert, both detectors were in operation with partial configurations. Each follow-up has been performed by looking for a signal excess around the best Active Galactic Nuclei (AGN) counterpart position. A standard time window of ±1 day around the IceCube alerts, as well as an extended search time window of 1 month, have been tested. The analyses and their results, including statistical significance, are reported here.
