Meriam Ibrahim has not been freed. The story I posted earlier was incorrect.
She was arrested once again while she and her family were at the airport, awaiting a flight to leave the country.
According to The Independent, the new charge is that she was using a passport obtained from South Sudan. Sudan does not recognize her as a South Sudanese citizen because it does not recognize her marriage to her Christian husband. Her husband has South-Sudan/American citizenship.
Mrs Ibrahim is being charged with forging her passport, a crime that is punishable by up to seven years in prison. She is being held in a Khartoum police station. Her family has refused to leave without her.
