THE HAGUE, Netherlands — Tens of thousands of red-clad protesters marched through the Dutch capital Sunday to demand their government do more to halt Israel’s campaign in Gaza, in what organizers called the country’s biggest demonstration in two decades.

Human rights groups and aid agencies — including Amnesty International, Save the Children and Doctors Without Borders — estimated the peaceful crowd at more than 100,000 people.

The protesters marched past the Peace Palace, headquarters of the United Nations’ International Court of Justice, where last year judges ordered Israel to do all it can to prevent death, destruction and any acts of genocide in Gaza.

As the protest wound its way past the court, canals and the seat of the Netherlands’ right-wing government, Israeli forces continued to pound northern Gaza, where they have launched new ground operations.

Airstrikes in the offensive killed at least 103 people, including dozens of children, overnight and into Sunday, hospitals and medics said, and forced northern Gaza’s main hospital to close.
