Germany’s chancellor and president strongly denounced a rise in antisemitism in Germany in the wake of the Israel-Hamas war in separate appearances Sunday that stressed the same idea that it is unacceptable for such hatred to flourish in the nation that perpetrated the Holocaust.

In Berlin, thousands of people gathered at a demonstration called to show opposition to antisemitism and support for Israel. People carried Israeli flags or posters with photos of some of the people reported to be missing or held by Hamas as hostages.

The protest, organized by a broad alliance of various organizations, comes as antisemitic incidents have been rising in Germany following the violent escalation of the war in Gaza. The organizers estimated that over 20,000 people took part; police put the number at 10,000.
