BUDAPEST, Hungary — Vigils, commemorations and acts of remembrance were planned across the world on Monday to mark one year since the Oct. 7 Hamas attack on Israel as world leaders called for an end to antisemitism and the release of Israeli hostages. [time-brightcove not-tgx=”true”] Last year’s surprise cross-border attack, which killed about 1,200 people, caught Israel unprepared on a major Jewish holiday, shattering Israelis’ sense of security and putting many countries, already on edge over Russia’s war in Ukraine, facing the prospect of another major conflict in the Middle East. The nations of Europe, home to many Jewish and Muslim communities, have sought to tamp down both antisemitic and anti-Muslim sentiment in the wake of the Hamas attack and Israel’s subsequent war against the militants in Gaza, which has killed over 41,000 people and displaced around 1.9 million in the embattled coastal territory. The German chancellery in Berlin was adorned with a yellow ribbon commemorating the Israeli hostages taken by Hamas, around 100 of which remain in captivity, with many of them feared dead.
