Ukraine's leader, Volodymyr Zelensky, has confirmed that China has urged Russia not to use nuclear weapons in the ongoing conflict, sparking widespread concern over the potential for escalation. Speaking in a televised address, Zelensky revealed that the Chinese government had explicitly warned [Russian President Vladimir] Putin that 'there can be no thought whatsoever of using nuclear weapons'. The warning is a significant development in the Ukraine-Russia war, which has been ongoing since February, with both sides suffering heavy losses and civilians caught in the crossfire. Zelensky's statement comes as fuel shortages begin to take hold in Russia, with long queues forming at petrol stations across the country overnight.
