A Muslim teenager who was ordered by a school monitor to take off a headscarf she wore for religious reasons returned to classes after school officials apologized to the family. Issra Omer, 13, told her parents she was too embarrassed to show up for summer school classes at Seaside High School on Wednesday, the day after a monitor demanded she remove her hijab, the Muslim scarf covering the head and neck, to conform to the district's no-hat policy. Issra, whose family is originally from Sudan, explained that her scarf is worn for religious reasons, but the school employee still yelled at her, said her father, Yousif Omer. The teenager felt humiliated by being singled out in front of her peers and started crying, he said. The school's principal, Syd Renwick, explained the employee did not intend any harm.
