The reports that Meriam Ibrahim was going to be released from prison were premature, according to the BBC.
Reports on Saturday said a Sudanese official had confirmed that Meriam Ibrahim, who gave birth in custody, would be freed in a few days.
But the foreign ministry said on Sunday Ms Ibrahim could only be released after a successful judicial appeal.
Her death sentence has sparked international outrage.
Ms Ibrahim was brought up as an Orthodox Christian, but a judge ruled last month that she should be regarded as Muslim because that had been her father’s faith.
She refused to renounce her Christianity and now faces hanging for apostasy.
It looks almost as if they’re teasing the world – “You think we’re outrageous? We’ll show you outrageous!” Never mind killing people for actually leaving Islam, now it’s killing people for being raised Christian when their fathers were Muslim. How would a state even administer that?
Last Wednesday, Ms Ibrahim gave birth to a daughter in her prison cell – the second child from her marriage in 2011 to Daniel Wani, a US citizen.
The court had said Ms Ibrahim would be allowed to nurse her baby for two years before the sentence was carried out.
The court also annulled her Christian marriage and sentenced her to 100 lashes for adultery because the union was not considered valid under Islamic law.
It’s all do everything retroactively with this guy. She thought she was Christian so she had a Christian marriage but oh no, the court says she started out as a baby Muslim because of Daddy so that Christian marriage turns out to be adultery. It’s all random arbitrary hahaha you can’t possibly predict this so we can punish you no matter WHAT you do type law.
In his interview with the BBC, Mr Wani said he was hoping to continue living in Sudan with his wife and children in the event of her release, but that that might be too difficult.
He also expressed his hope that the court would reconsider the verdict about the annulment of their marriage, which he confirmed he had also appealed against.
Bad idea, I think. Their legal system just looks too capricious for safety.
