In 2017, the Saudi blockade of Yemen caused fuel costs to rise by over 100% in Sanaa, crippling transport systems and making it even harder for people to access clean water, food, and healthcare. By August 2019, the price of diesel had reached 430 riyals per liter, which was a 186.7% increase from the pre-war price; at the same time, the price of gasoline had risen to 365 riyals per liter, which was a 143.3% increase over the same period.
