Iran says it is fully prepared to counter widened US economic sanctions, according to Iranian state media. The US calls its latest sanctions on Iran an economic D-Day, but Tehran says it has a plan to counter them. The US has imposed new sanctions on Iran's oil and petrochemical sectors, targeting several companies and individuals. The sanctions are part of a broader effort to increase pressure on Iran over its nuclear programme. The US has said the sanctions are aimed at cutting off Iran's revenue from oil exports, which are a key source of income for the country. Iran has said it will continue to export oil despite the sanctions. The country has also said it will take action against any country that tries to enforce the sanctions. The US has called the sanctions an economic D-Day for Iran, saying they will have a significant impact on the country's economy. However, Iran has said it is fully prepared to counter the sanctions, and has a plan in place to mitigate their impact. The sanctions are the latest in a long-running dispute between the US and Iran over the country's nuclear programme. The US has imposed several rounds of sanctions on Iran in recent years, in an effort to pressure the country to limit its nuclear activities. Iran has consistently denied any intention to develop nuclear weapons, and has said its nuclear programme is for peaceful purposes only. The sanctions have had a significant impact on Iran's economy, but the country has said it will continue to export oil and other goods despite the restrictions. The US has also said it will continue to enforce the sanctions, and will take action against any country that tries to evade them. The situation is likely to remain tense in the coming weeks and months, as the US and Iran continue to engage in a high-stakes game of economic and diplomatic pressure.
