Linked ITAR-TASS source says that the rise in that week was just 0.05 roubles per liter with the price around 55 roubles. Not sure where the 10% figure comes from, either some other source was used, or it was not translated correctly (mistook “5 копеек” (.05 rub) for 5 roubles)
The corruption is crazy, but like 70% of the corruption is just Clarence Thomas. Like, he manages to be the embodiment of corruption in justice system.
