In a dramatic escalation of tensions, Iran's Islamic Revolutionary Guard Corps (IRGC) has warned that it will cease oil and gas supplies to the US and its allies for years, signaling an end to its previous restraint. This warning follows US President Donald Trump's ultimatum for a ceasefire, threatening military action if Iran does not comply by 8pm ET (1am BST on Wednesday). The IRGC's announcement, made via Telegram, indicated that they would target US infrastructure in the region, stating, 'Restraint is Over.' This comes amidst reports of US and Israeli forces striking Kharg Island, Iran's main oil export terminal, with explosions heard in nearby coastal areas. The conflict has raised concerns about the stability of oil supplies from the region, which is crucial for global markets. Additionally, retired US Army Lt Gen Mark Hertling has suggested that some military commanders may be preparing to disobey Trump's orders regarding the conflict, adding further uncertainty to the situation.
