A Sudanese Christian woman just released after being sentenced to death for apostasy has been re-arrested with her family at Khartoum airport, according to her lawyer

Meriam Ibrahim, 27, was freed on Monday after a Sudanese appeal court reversed her conviction for abandoning Islam and adultery. Her husband Daniel Wani said the family intended to leave for the US. But about 40 security agents detained Ibrahim along with Wani and two sons at the airport.

Born to a Christian mother and a Muslim father, Ibrahim was sentenced to death by hanging under the country's strict Sharia laws after she married a Christian, Daniel Wani, in 2011.

In Sudan interfaith marriage is forbidden and, according to Islamic law, children inherit the father's religion while the mother's line is considered irrelevant.

Ibrahim claimed she was raised as a Christian and refused to renounce her faith. She was subsequently accused of renouncing Islam through her marriage and sentenced to death.

She was also sentenced to 100 lashes after being convicted of adultery, as her marriage was deemed invalid.

Ibrahim was thrown in jail with her 20-month-old son, and gave birth to a baby girl while in chains.

Her case sparked global outrage with the British government calling on Sudan to release her.
