Iran is ranked third on Open Doors’ World Watch List for countries with the worst persecution of Christians. The U.S. Commission on International Religious Freedom also lists Iran as a “Country of Particular Concern,” a label given to countries with the worst religious freedom abuses.

According to the CIA World Factbook, 98 percent of Iran's population is Muslim while Christians, Jews, Baha'is, and Zoroastrians comprise the remaining two percent.
