“We woke up on November 12, the day that I will never forget my whole life,” Sara, 18, told CNN in a recent interview, holding back tears.

More than 20 people, relatives and neighbors, had holed up at their house as the war worsened. Sara’s 57-year-old mother, Hala, cooked a quick breakfast and made time to pray. Then they heard their neighbors screaming that an evacuation route had been organized: “Come on, get out!”

They threw on their shoes and rushed out of the door, joining a wave of others waving white flags – a universal symbol of surrender.

A few paces ahead of the others, Hala was walking with her grandson, Tayem, then 4, holding hands as they navigated a street littered with debris, a white flag in his other hand. Seconds later, a shot rang out and Hala slumped to the ground.
