Brussels became the stage for one of Europe’s largest solidarity demonstrations in recent years as tens of thousands of people filled the streets to demand stronger action for Gaza. Organizers estimate that as many as 110,000 people joined, while police put the figure closer to 70,000. Whatever the number, the sight was striking. Protesters dressed in red and carried red cards to symbolize a warning to political leaders who they say have failed to stop the suffering of Palestinians.
Message Behind the Red Line
The demonstration was organized under the banner Red Line for Gaza. For participants, the message was clear: Europe must not continue to cross the line of inaction while civilians in Gaza face devastating conditions. The choice of red clothing and props was deliberate, creating a river of color through the city center that drew international media attention.

Protesters marched peacefully but passionately, chanting for justice, accountability, and immediate humanitarian aid.
Political Context in Belgium and Beyond
The timing of the march was especially significant. Belgium recently announced its intention to recognize a Palestinian state at the United Nations General Assembly, becoming one of the first European countries to take such a step.
The government also suggested that it could impose sanctions on Israel if conditions on the ground did not improve. Protesters welcomed these announcements but insisted they were not enough.
The Brussels march was not an isolated event. Across Europe, similar demonstrations have taken place, including a huge rally in The Hague where more than 100,000 people surrounded the International Court of Justice. These parallel movements show that concern for Gaza is not only a Belgian issue but a wider European demand for justice and accountability
