The United States condemns the conviction of Pastor Youcef Nadarkhani. Pastor Nadarkhani has done nothing more than maintain his devout faith, which is a universal right for all people. That the Iranian authorities would try to force him to renounce that faith violates the religious values they claim to defend, crosses all bounds of decency, and breaches Iran’s own international obligations. A decision to impose the death penalty would further demonstrate the Iranian authorities’ utter disregard for religious freedom, and highlight Iran’s continuing violation of the universal rights of its citizens. We call upon the Iranian authorities to release Pastor Nadarkhani, and demonstrate a commitment to basic, universal human rights, including freedom of religion.
Update: I also see a USCIRF statement there.
Marco Rubio has a piece here as well.
