How did fresh US sanctions affect Iran?
Iran has some of the cheapest fuel prices in the world due to heavy subsidies and the downturn in its currency.
It is also one of the largest producers of oil in the world, with exports worth billions of dollars each year. But it has limited refining capacity and sanctions make it difficult to obtain spare parts for oil plants.
The sanctions were restored last year after US President Donald Trump abandoned a landmark nuclear deal between Iran and six world powers.
Under the Agreement, Iran has agreed to limit its conflicting nuclear activities and allow international inspectors in return for sanctions relief. to want to develop nuclear weapons.
The sanctions led to a sharp decline in Iran's economy, pushing its currency to record levels, doubling its annual inflation, driving foreign investors away, and sparking protests.
