$\Lambda$, $\Xi$ and $\Omega$ yields and transverse mass spectra have been measured at central rapidity in Pb-Pb and p-Pb collisions at 158~A~GeV/$c$. The yields in Pb-Pb interactions are presente d as a function of the collision centrality and compared with those obtained from p-Pb collisions. Strangeness enhancement is observed which increases with centrality and with the strangeness co ntent of the hyperon.
