Hebrew graffiti thanking Adolf Hitler and denouncing Zionism have been sprayed inside Israel's own Holocaust museum in Jerusalem.

One giant slogan at the Yad Vashem museum in Jerusalem read: 'Thank you Hitler for your wonderful Holocaust that you arranged for us, it's only because of you that we got a state at the UN.'

It was sprayed across walls in Warsaw Ghetto Square near to a sculpture depicting the Warsaw Ghetto uprising, in which 13,000 were killed in the first uprising in Nazi occupied Europe....

That slogan fuelled suspicion that a small fringe of ultra-Orthodox Jews, who are virulently opposed to the state of Israel, were to blame....
