Fuel stations in Moscow and St. Petersburg, Russia, have begun limiting gasoline purchases to between 20 and 100 liters per customer. Shortages have also been reported in the Tatarstan region. Authorities attribute the restrictions to preventative measures designed to curb panic buying and stabilize the fuel market. Energy companies echo this explanation, emphasizing the goal is to avoid exacerbating existing tensions. The limits vary depending on fuel type and the specific gas station operator, according to UNN news agency reports. These actions suggest underlying concerns about fuel supply within key Russian regions, though officials maintain the situation is under control.
