More than 100,000 people gathered Sunday in The Hague to protest the Dutch government’s stance on Israel and the ongoing war in the Gaza Strip, in what organizers called the Netherlands’ largest demonstration in the past 20 years, according to NOS.

Participants wore red clothing to symbolically draw a “red line,” a message aimed at the Dutch government, demanding it take action against what they described as Israel’s continued violations of international humanitarian law. “Prime Minister Schoof refuses to draw a red line. That’s why we’re doing it,” organizers stated.
