Israel's Prime Minister Benjamin Netanyahu has been criticised for saying a Palestinian leader persuaded the Nazis to carry out the Holocaust.
Mr Netanyahu insisted Adolf Hitler had only wanted to expel Jews from Europe, but that Grand Mufti of Jerusalem Haj Amin al-Husseini told him: "Burn them."
However, the chief historian at Israel's memorial to the Holocaust said this account was factually incorrect.
Speaking alongside Mrs Merkel in Berlin, Mr Netanyahu said "no one should deny that Hitler was responsible for the Holocaust".
But Mr Netanyahu insisted the Mufti of Jerusalem "told the Nazis to prevent Jews fleeing from Europe and supported the Final Solution".
