Sudan's government is considering reversing the death sentence passed on Meriam Ibrahim, who faces hanging for refusing to renounce her Christian faith.

A representative from neighbouring South Sudan said it had approached the government in Khartoum and offered to mediate - because Ms Ibrahim's husband, Daniel Wani, was born in the South.

Sentenced to death: Meriam Ibrahim on her wedding day.

"The authorities have expressed readiness to examine the case and see how it could be handled with mutual respect," Charles Manyang, the under-secretary for South Sudan's foreign affairs ministry, told The Sudan Tribune. "The response we got was positive."

President Omar al-Bashir, who has imposed Islamic law on Sudan, has come under increasing pressure since the sentencing of Ms Ibrahim, 27, for apostasy on May 15.
