  Neutrino oscillations in the presence of strong gravitational fields are
studied. We look at very high energy neutrinos ($\sim $1 TeV) emanating from
Active Galactic Nuclei (AGN). It is observed that spin flavor resonant
transitions of such neutrinos may occur in the vicinity of AGN due to {\it
gravitational} effects and due to the presence of a large magnetic field ($\sim
$1 Tesla). A point to note is that matter effects (normal MSW transitions)
become negligible in comparison o gravitational effects in our scenario.
