Iran’s state news agency is reporting that authorities have imposed rationing and increased the prices of fuel.

IRNA's report early Friday said every private car will have a 60-liter monthly quota at about 13 cents per liter, up from 9 cents. Taxis and ambulances have a quota of up to 500 liters at 13 cents. Beyond that, the price is 26 cents per liter.

In 2015, Iran stopped fuel rationing that had been in place since 2007.

The decision came following months of speculations about possible rationing after the U.S. in 2018 reimposed sanctions that sent Iran’s economy into free-fall following Washington withdrawal from 2015 nuclear deal between Iran and world powers.

President Hassan Rouhani said Tuesday Iran in recent months has faced its “the most difficult” time in decades.
