A vector meson exchange model based on effective Lagrangians is used to build the meson--baryon interaction in the charm +1, strangeness -2 and isospin 0 sector. The s-wave scattering amplitudes resulting from the unitarization in coupled-channels show two resonances with masses and widths that are in very good agreement with those of the experimental Ωc(3050)0 and Ωc(3090)0 states observed by the LHCb collaboration. The interpretation of these resonances as pseudoscalar meson--baryon molecules would mean the assignment JP=1/2- to their spin--parity.
