          Abstract

          Recently ANTARES collaboration presented a time dependent analysis to a selected number of flaring blazars to look for upward going muon events produced from the charge current interaction of the muon neutrinos. We use the same list of flaring blazars to look for possible positional correlation with the IceCube neutrino events. We observed that six FSRQs and two BL Lac objects from the list are within the error circles of eight IceCube events. We also observed that three FSRQs are within the error circles of more than one event. In the context of photohadronic model we propose that these neutrinos are produced within the nuclear region of the blazar where Fermi accelerated high energy protons interact with the background synchrotron/SSC photons.
