An American citizen whose pregnant wife has been sentenced to death in Sudan for refusing to renounce her Christian faith told Fox News’ Greta Van Susteren Friday that his wife is staying strong in her convictions despite her ordeal.

Meriam Yehya Ibrahim, 27, whose Christian husband Daniel Wani holds American citizenship, has been held in a Sudanese prison along with her 20-month old son for more than three months.

Last week, in a decision that drew international condemnation, a judge in Khartoum sentenced her to death by hanging once she gives birth and nurses her child for two years, because she would not renounce her Christianity.

Wani said on “On the Record with Greta Van Susteren” that when his wife’s ordeal began he went to the U.S. embassy and tried to report the case. However, he said he was told to go to the UN because his wife is not an American.

“I say I am an American and she is a doctor, you have to help her but she refuse to do anything,” Wani said of a counselor at the embassy he spoke to.

U.S. lawmakers including GOP Sens. Marco Rubio and Kelly Ayotte have pressed the Obama administration to grant asylum to Ibrahim.

Wani said the conditions in the prison are “not good.”

“Her mood is not good…as you know, prison is not a good place,” he said.

However he said despite her ordeal, Ibrahim is staying strong in her convictions.

“She said she is not going to convert to Islam,” he said. “And let them do whatever they want to do but she is still a Christian and she is a Christian since she was born.”

Wani said on that those want to help his wife should pressure the Sudanese government to set her free.
