(CNN) Germany's anti-Semitism commissioner has asked all citizens to wear the kippah in solidarity with the Jewish community, in the run-up to planned anti-Israel protests Saturday.

"I call on all citizens of Berlin and across Germany to wear the yarmulke (as the skullcap is known in Yiddish) next Saturday if there are new, intolerable attacks targeting Israel and Jews on the occasion of Al-Quds Day in Berlin," said Felix Klein in a statement.

"By doing this we can show a great sign of solidarity with the Jewish community and make a statement for the freedom of religion and the diversity of our society," Klein told CNN via email.

Al-Quds Day is an annual event marked by protests against Israel, on the last Friday of Ramadan, with attendees expressing support for Palestinians.

Demonstrations, parades, and seminars are held in various countries, but are especially large in Iran, where Al-Quds Day was established in August 1979. Al-Quds is Arabic for Jerusalem.
