Twelve hundred people in Israel were killed on Oct. 7, 2023, and around 100 hostages are still being held captive by Hamas.
Outside the synagogue in southwest Houston, empty chairs represent those who have still not come home.
"We have to make a point that all hostages should come back," Nitza Hampel said with resolve. "There is never a thing like that to grab people just because you want to."
Members of 50 Houston-area Jewish Organizations packed the room. The vigil, which focused on "Remembrance, Unity, and Hope," included song, prayer, and remarks from community leaders.
"We stand strong," Burt Levine of the Jewish War Veterans of Houston told ABC13.
