Police said 18 graves in the town’s Jewish cemetery were vandalized, with some tombstones knocked over and broken. They asked the public to help in finding the culprits, whom they said were nationalistically motivated

Police estimated the damage amounted to several thousand euros.

The attack came as the area celebrated 20 years since the Jewish community was revived after the Holocaust. The community is today centered in nearby Oldenburg.

Some 300 Jews live in the area today, with 90% of them hailing from the former Soviet Union, according to the Jewish Virtual Library.

The communities of Oldenburg

and Delmenhorst are served by Rabbi Alina Treiger, the first female rabbi to be ordained in Germany since before the Holocaust.
