France Investigates Possible Russian Link to Star of David Graffiti in Paris

PARIS—Prosecutors are investigating a possible Russian connection to more than 200 Jewish stars spray painted on buildings in France, where antisemitic acts have been sharply rising.

The mysterious appearance of the blue stars on a seemingly random assortment of buildings last week sent a fresh bolt of concern through France, where tensions have mounted since Hamas’s attack on Israel. France is home to some of Europe’s largest Muslim and Jewish populations.
