LONDON — The night before Khadiza Sultana left for Syria she was dancing in her teenage bedroom. It was a Monday during the February school vacation. Her niece and close friend, at 13 only three years younger than Khadiza, had come for a sleepover. The two girls wore matching pajamas and giggled as they gyrated in unison to the beat.
Khadiza offered her niece her room that night and shared a bed with her mother. She was a devoted daughter, particularly since her father had died.
