The Sudanese doctor who married the Christian man was convicted earlier this week on charges of apostasy.

According to the Sudanese officials, 26-year-old Meriam Ibrahim, whose father was Muslim, was convicted on Sunday and given four days to repent and escape death. She was sentenced after that grace period expired, the officials said, speaking on condition of anonymity.

The sentencing drew condemnation from western embassies in the Sudanese capital, Khartoum, and international rights groups, including Amnesty International.

The court in Khartoum also ordered Ibrahim be given 100 lashes for committing zina – an Arabic word for illegitimate sex – for having sexual relations with a non-Muslim man.

The couple married in 2011 and have a child, born 18 months ago. Sudanese law does not recognise Ibrahim’s marriage to a non-Muslim.

Ibrahim can appeal against her death sentence as well as the 100 lashes reports the Guardian.

As in many Muslim nations, Muslim women in Sudan are prohibited from marrying non-Muslims, though Muslim men can marry outside their faith. By law, children must follow their father’s religion.

Amnesty International said Ibrahim’s conviction and death sentence were “truly abhorrent”.

Sudan’s current ruler, Omar al-Bashir, is an Islamist who seized power in a 1989 coup.
