BESLAN, Russia — Zalina Dzandarova cradles her son Alan as he sleeps with his small face buried against her stomach. He is the child Dzandarova was able to save. The child she chose to save, really. It is the other one, little Alana, her 6-year-old daughter, whose image torments her: Alana clutching her hand, Alana crying and calling after her. Alana's sobs disappearing into the distance as Dzandarova walked out of Middle School No. 1 here Thursday, clutching 2-year-old Alan in her arms.
