'I've been waiting here for five hours!' one woman shouts. Putin recently acknowledged that the country was facing 'a certain shortage' of fuel after repeated Ukrainian strikes in their four-year war.'As for strikes against critical infrastructure in general, and energy infrastructure in particular, of course these attacks on our infrastructure facilities create problems, that's obvious,' Putin said.'Right now we're observing a certain shortage, but it's not critical.'Authorities in Russian-annexed Crimea recently declared an 'emergency situation' over fuel shortages and power cuts triggered by Ukrainian attacks on logistics chains and oil facilities.Addressing the United Russia party congress, Putin said: 'You're well aware that problems persist for both motorists and businesses.'Unfortunately, there are still queues at petrol stations, and finding the right grade of petrol isn't always easy.'In Crimea, Putin admitted, only 'a few days' supply' of fuel was left – but said he was 'confident' more would be brought in soon.He also vowed to ensure Russia's security and overcome the challenges posed by Ukraine's increasingly frequent strikes inside the country.'Yes, we see the problems, we are aware of them and are responding to them, but we will certainly ensure the security of both the country and our citizens, as well as the inviolability of Russia's borders,' Putin told party members.It comes as over the weekend, Ukraine launched a 'massive' drone attack on a Russian oil terminal in St Petersburg overnight as Kyiv presses on with bombardment targeting Vladimir Putin's infrastructure.Aleksandr Beglov, the governor of St Petersburg, admitted the port had been hit but reported no casualties. He said Russian air defences had shot down 72 Ukrainian drones across Russia's second-largest city and the surrounding region.Volodymyr Zelensky described the port as an 'important military target' which 'generates revenue for Russia's war' on Kyiv. On Saturday morning, the Ukrainian president said: 'Last night, our Ukrainian long-range sanctions against Russia over this war reached targets near St. Petersburg. 'Ukraine's Defense Forces struck port oil infrastructure that generates revenue for Russia's war, and there were also successful strikes on Kronstadt – an important military target.

My thanks to everyone who is ensuring Ukraine's precision and carrying out our long-range sanctions plan. Glory to Ukraine!' Almost daily long-range attacks on Russian oil facilities have created a fuel crisis and heaped political pressure on the Kremlin as its invasion stretches into its fifth year.St. Petersburg's Kirovsky district was previously hit in June, ahead of Russia's flagship St. Petersburg International Economic Forum.The Crimean peninsula, which Russia annexed in 2014, has suffered particularly from heavy strikes, causing local authorities to suspend gasoline sales to civilians. A Ukrainian attack on Saturday killed one person and injured two more, including a 10-year-old child, said the Moscow-installed St Petersburg governor. Vladimir Putin has shrugged off Ukraine's strikes on Russia's energy facilities as 'not critical,' and insisted the war will continue until his goals are met.He has described the attacks as an effort by Kyiv to distract attention from its losses on the battlefield, although analysts have said the advance of Russian forces has been stymied in recent months.Ukraine has said that nearly 43 per cent of Russia's oil refinery capacity has been 'disabled' following its attacks, however this claim has not been verified independently. But Kyiv has insisted that Russian energy facilities are legitimate military targets because Russia heavily relies on oil exports to fund its invasion, launched in February 2022. The Russian defence ministry has responded to the attacks by saying they 'will not go unanswered'. On Friday, Putin visited the Russian military headquarters directing the war in Ukraine and received a report on the capture of the city of Kostyantynivka after weeks of intense street battles. He hailed it as a key step toward capturing the nearby cities of Sloviansk and Kramatorsk, the key remaining strongholds in the so-called 'forest belt' of heavily fortified cities in the Donetsk region that remain in Ukraine's hands.The capture of Kostyantynivka, a big transport and industrial hub, is of 'major strategic importance,' Putin, clad in military fatigues, said in televised comments.In a briefing on Saturday, Sergei Rudskoy, the first deputy chief of the general staff of the Russian armed forces, said Ukrainian troops had been pushed back several kilometers and that fighting was taking place on the outskirts of the nearby town of Oleksiievo-Druzhkivka.
