Iran sits in the heart of the Middle East, sharing borders with Turkey, Iraq and Afghanistan, among others. Formerly known as Persia, it was once a great empire of the ancient world.
The country became an Islamic Republic in 1979, when the monarchy was overthrown during the Iranian Revolution, and political control passed to the clerics.
Médecins Sans Frontières/Doctors Without Borders (MSF) first worked in Iran in 1990. Projects have focused on people who would not otherwise have access to healthcare, including vulnerable groups such as sex workers and street children.
