A Jewish cemetery in western Poland and a Holocaust memorial site in Russia were defaced in suspected anti-Semitic attacks this week.

In Kalisz, near Wroclaw, a Star of David on a gallows and the inscription "Kalisz without Jews" (Kalisz bez Żydów) were spray-painted on a Jewish cemetery and discovered on Thursday, according to naszemiasto.pl, a news site.

The same slogan appeared on a large banner that was placed at one of the city’s main streets in 1939 to greet the advancing Nazi forces.

Local police were informed of the incident, the website reported.
