Saeed Abedini is shown here with his 4-year-old son.
An American Christian pastor being tried in Iran for his religious beliefs was "shut out" of his own trial Tuesday, a religious group said.
The attorney for Saeed Abedini also was kept from appearing in the Iranian court, said the American Center for Law and Justice.
Abedini, who was born in Iran and now lives in Idaho, has been jailed since September, the group said.
A lay church leader, testified in court Tuesday about his connection to Abedini, said the center, a right-leaning organization founded by television evangelist Pat Robertson.
"This individual was specifically questioned about converting to Christianity and whether Saeed encouraged the conversion to Christianity, which he did," the center said. "Additionally, the court asked for details about how Pastor Saeed has financed his multiple trips back to Iran to work on establishing an orphanage for children in need and whether any foreign funds were involved."
The judge told the lay leader to expect another summons within a month to return to court, said the pastor's wife, Naghmeh Abedini.
Naghmed Abedini said her husband had earlier told her that he will likely be held "in prison for a long time," she said in a statement through the center.
"This testimony today is further proof that Iran was just trying to silence the media and has no intention of releasing my husband anytime soon," her statement said. "We need to continue exposing Iran's violations of Saeed's human rights until my husband is safely back in my arms."
Abedini's trial began Monday when he and his attorney appeared in a Revolutionary Guard Court to address charges of attempting to undermine the Iranian government, the center said.
The group contends that charges stem from Abedini's conversion to Christianity to Islam 13 years ago and his activities with home churches in Iran.
On Monday, the pastor gave the judge a written statement and was questioned by prosecutors and his defense lawyer, whom he only met that day.
The judge in the case has faced sanctions by the European Union "because of his harsh sentences for those on trial for exercising a fundamental human right," the center said.
Naghmeh Abedini said this week that "a few" laymen with the Christian church in Iran told her husband's attorney that they have been called to testify in the case.
Tiffany Barrans, the legal director for the American Center for Law and Justice, said this week that the church leaders in Iran were faced with a dilemma: They could avoid being witnesses, or they could testify in court and possibly face similar charges
"They are all very fearful to have to show up," she said on a conference call with Naghmeh Abedini and Jordan Sekulow, executive director of the nonprofit organization, which provides legal counsel and litigates cases involving freedom and liberty issues around the world.
