New results on rare kaon decays in NA48

The main purpose of the NA48 experiment at CERN is the measurement of the direct CP violation parameter $Re({\epsilon}'/ \epsilon)$. In addition it offers a competitive program on rare $K_L$ and $K_s$ decays. In the following resent results of the decays $Ks \to \gamma \gamma , Ks \to \pi^0e^+e^-$, $K_{s,L} \to \pi^+\pi^-e^+e^-$ and $K_L \to 3\pi^{\circ}$ are presented.
