A memorial stone marking the site of a former synagogue destroyed by the Nazis has been vandalised in Strasbourg.

Officials said the heavy memorial stone was discovered moved from its base in the French city on Saturday morning.

Strasbourg mayor Roland Ries denounced the incident as “a new antisemitic act”.

French officials in the region said that antisemitism “undermines the values of the republic”.

The monument commemorates a synagogue built in 1898 that was set on fire and razed to the ground by the Nazis in 1940.
