Sudanese authorities reportedly stopped Meriam Ibrahim because she used her “Christian name” on her passport and visa to leave for the United States rather than her “birth Islamic name.”

“The State Department has been informed by the Sudanese Government that the family was temporarily detained at the airport for several hours by the government for questioning over issues related to their travel and I think travel documents. They have not been arrested. The government has assured us of their safety,” said State Department spokeswoman Marie Harf.

“The Embassy has been and will remain highly involved in working with the family and the government,” Harf continued. “We are engaging directly with Sudanese officials to secure their safe and swift departure from Sudan, and of course, we’ll provide more information as we get it.”

Ibrahim is reportedly at a friend’s home after bail was posted for her. However, Ibrahim’s attorneys say that if she leaves the country, the government will penalize the person who posted bail.

Tina Ramirez, the founder of the electronic activist group Hardwired, said that the United States is responsible for the problems because they did not coordinate Ibrahim’s departure from the country with the Sudanese government.
