Egyptian border guards shot a Sudanese refugee and arrested two others early Wednesday as they tried to cross from Egypt into Israel, a police official said. Twenty-six other refugees were successful in the their attempt to illegally cross the border, the official said. The Israeli army, meanwhile, said 47 Africans crossed the border from Egypt overnight, without specifying nationalities. The army did not provide more details. Security officials shot one Sudanese refugee, who did not have a passport, when he did not comply with orders to turn himself over to authorities, said the official, who spoke on condition of anonymity because he was not authorized to speak to the media. The refugee was taken to an Egyptian hospital, and his condition was "very critical," according to the official. Authorities arrested two other Sudanese refugees, Rawda Abdullah, 25, and her 24-year-old brother Ismail, who were from the war-torn Darfur region, as they tried to cross the border. They remain in police custody.
