'**** you! I'll smash your face in!' one of them shouts.

In one region, police were forced to crackdown on a mafia group which resold petrol at triple the price. It comes after Putin acknowledged that the country was facing 'a certain shortage' of fuel in an interview published by the Kremlin on Sunday, 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 on Friday declared an 'emergency situation' over fuel shortages and power cuts triggered by Ukrainian attacks on logistics chains and oil facilities.A few hours earlier, 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.
