Protesters expressed anger over high inflation and increasing economic hardship caused in part by the dramatic decline of the national currency, the rial, which has been hit by U.S. plans to reimpose sanctions on August 7 on Iran's purchase of U.S. dollars.

In Washington, the U.S. State Department said on its Persian-language Twitter account on August 3, "While it is ultimately up to the people of Iran to determine their country's path, America supports the voice of the Iranian people, which has been ignored for a long time."
