“Uniting our memories is a common good,” Mr Iohannis added.

As many as 380,000 Jews were killed in Romanian territories during the Second World War, according to Yad Vashem.
Before the war, Romania had a Jewish population of about 757,000. However, latest estimates say they now number only 8,000, of which less than 4,000 are ‘registered’ Jews.
This means a 99.56 per cent reduction in Jewish population since before the war.
It took until 2003 for the Romanian government to recognise the role it had played in the Holocaust, which saw the Iron Guard — Romania’s fascist movement — beat Jews and loot their shops, before the Romanian Army began ethnic cleansing through mass killings of Jews and long marches to concentration camps.
