JTA – Polish authorities are unclear if graffiti painted on a gallery near Warsaw’s Academy of Fine Arts not far from an opening of an Israeli photographer’s exhibition was meant as an anti-Semitic attack.

The slogan “I Miss You Jew” was painted on a gallery owned by Polish businessman Wojciech Fibak late Monday night, according to Haaretz. Nearby, an exhibit by Israeli artist Diti Ravner, the wife of Israeli envoy to Poland Zvi Ravner, was held.

Ravner’s photos feature Jewish life in Warsaw today.

Two similar inscriptions were painted on other art-related buildings in the city on the same night, according to the newspaper. Authorities are investigating the case.
