A Iranian-American pastor, Saeed Abedini, has reportedly been arrested and charged in Iran while visiting his family.
Reports say the 32-year-old Christian convert has been detained in Tehran’s Evin prison since late September.
The charges against him are not clear.
The American Center for Law and Justice, which is representing his wife, has alleged that Abedini was jailed because of his Christian faith.
The group says it is launching a campaign to demand the release of the pastor, who became a U.S. citizen in 2010.
Earlier this year, Iran released pastor Youcef Naderkhani, a Christian convert, who had reportedly been sentenced to death for apostasy for refusing to renounce his faith.
In the Islamic republic, a Muslim who converts to another faith can face the death penalty.
