A 27-year-old woman who was sentenced to death in Sudan last month for converting to Christianity from Islam was freed Monday after what the government said was "unprecedented" international pressure.

Mariam Yahya Ibrahim, who is married to a Christian American, was ordered by a Sudanese court last month to return to Islam and was sentenced to 100 lashes and to death.

Her release is likely to be welcomed by human rights groups and Western governments who voiced outrage at the ruling.
