“Between 9 and 12 months old, babies learn to stand, say their first word, maybe take their first steps. As the family of Kfir Bibas, the youngest Israeli held in captivity in Gaza, celebrated his first birthday without him, they wondered which, if any, of the typical milestones they missed during those three months of his life. “They’re supposed to see a lot of colors, but instead he’s seeing just darkness,” said Yosi Shnaider, a cousin. “He’s supposed to be learning to walk, but he has nowhere to do it. He’s supposed to be able to hold a spoon for the first time, he’s supposed to be tasting so many different foods for the first time.” Kfir, brother Ariel, and parents Shiri and Yarden Bibas were kidnapped Oct. 7 when Hamas attacked Israel, killing 1,200 people and taking about 250 hostage. On Thursday in Tel Aviv, hundreds of people gathered for what Shnaider called “the saddest birthday in the world.“ The infant with red hair and a toothless smile has become a symbol across Israel for the helplessness and anger over the 136 hostages still in captivity in Gaza.”
