The petrol crisis in Russia is reaching a tipping point,causing Vladimir Putin’s leadership to come under scrutiny.

Foreign officials have raised concerns about the dictator’s approach to the crisis – which has caused fist fights at petrol pumps – as he continues his war in Ukraine.

Estonian Foreign Minister Margus Tsahkna told RedaktionsNetzwerk Deutschland: ‘Even among the oligarchs,more and more are doubting Putin’s war. Many who spoke of victory a year ago no longer believe it.’

Ukrainian strikes on key oil facilities in Russia are causing serious harm to the economy.

Ukraine has vowed to stop the strikes if Putin halts his debilitating war – but he refuses to do so,at an increasing cost to Russians.

‘Putin could change his goals and enter into serious negotiations – if he acts rationally,’ Tsahkna added.
