  A meson-baryon interaction in the charm $+1$, strangeness $-2$ and isospin
$0$ sector is built from a t-channel vector meson exchange model employing
effective Lagrangians. The implementation of coupled-channel unitarization in
the s-wave scattering amplitudes gives rise to two structures that have similar
masses and widths to those of the $\Omega_c(3050)^0$ and $\Omega_c(3090)^0$
states recently observed by the LHCb collaboration. A meson-baryon molecular
interpretation of these resonances would assign their spin-parity to be
$J^P=1/2^-$.
