At exactly 6:29 a.m. on Wednesday, the fountain at Tel Aviv's Dizengoff Square ran red, dyed by activists marking the precise moment three years earlier when Hamas-led terrorists stormed across the Gaza border and began the deadliest attack in Israel's history. The installation became one of the day's most visible symbols of national mourning, with the crimson water standing in for the blood of the roughly 1,200 people killed on October 7, 2023. It was paired with another striking tribute at Trumpeldor Beach, where rows of painted human figures were laid across the sand to represent the victims who were murdered or taken hostage. Across the country, memorial events and moments of silence unfolded throughout the day, from the Nova festival site to Kibbutz Kfar Aza.

The red fountain was also tied to a broader wave of protest, with demonstrators using the anniversary to renew demands for a full state commission of inquiry into the government and military failures that preceded the attack. Activists briefly blocked Tel Aviv's Ayalon Highway at the same 6:29 a.m. mark, unfurling a banner reading that the people will remember their sons and daughters, while other protesters gathered outside the Prime Minister's Residence in Jerusalem. The demonstrations unfolded alongside official state ceremonies, including a memorial candle lit by President Isaac Herzog and his wife Michal, and came just weeks before a national election in which October 7 is expected to remain a central issue. Organizers said the red dye was meant not as political theater but as an unflinching visual reminder of what the country lost that morning.
