The International Monetary Fund (IMF) has visited Tehran for its first regular assessment of Iran's economy in nearly three years.
In a statement after the end of the January 25-February 8 visit, the head of the mission, Martin Cerisola, said Iran's economy faced deep structural challenges as intensified sanctions over Iran's nuclear program have added to other domestic challenges for the government.
The statement also said that "a combination of shocks" including increased sanctions had weakened the economy.
It said Iran now "stands at a crossroad" and urged reforms "to promote stability, investment, and productivity."
The IMF last visited Iran for a full economic review in July 2011.
