DUBAI (Reuters) – Iran is studying ways to keep exporting oil and other measures to counter U.S. economic sanctions, state news agency IRNA reported on Saturday.

Since last month, when U.S. President Donald Trump pulled out of the nuclear deal which lifted most sanctions in 2015, the rial currency has dropped up to 40 percent in value, prompting protests by bazaar traders usually loyal to the Islamist rulers.

Speaking after three days of those protests, supreme leader Ayatollah Ali Khamenei said the U.S. sanctions were aimed at turning Iranians against their government.
