The Netherlands inaugurated its National Holocaust Museum this Sunday in a ceremony presided over by King Willem-Alexander and Israeli President Isaac Herzog. Thousands of pro-Palestinian protesters gathered amid heightened security measures at Waterloo Square in central Amsterdam.

Rally leaders emphasized that they were protesting against Herzog's presence, not against the museum and what it commemorates. The museum, which will open this Monday to the public, is located in Plantage, the neighborhood that once welcomed Jews awaiting deportation from Amsterdam.
