On the Mount of Remembrance in Jerusalem is a solemn memorial to the victims of the Holocaust.
Six million Jews were systematically discriminated against in Nazi Germany and areas it occupied during World War II on the basis of their ethnicity, and killed.
Prime Minister Lee Hsien Loong yesterday visited the memorial, Yad Vashem, where he rekindled an eternal flame in their memory and laid a wreath in a solemn ceremony.
He wrote in the guestbook that he was deeply moved by the memorial: " 'Never again!' - but we have yet to realise that pledge in full measure. Mankind continues to inflict and suffer terrible and tragic violence. May the message of Yad Vashem inspire us to build a more peaceful world for future generations, and for all races and religions."
The memorial was designed by architect Moshe Safdie, who was also behind the Marina Bay Sands in Singapore. Mr Lee also visited the Israel Museum and viewed the Dead Sea Scrolls, one of the oldest surviving manuscripts of the Bible.
