US President Donald Trump has announced that a blockade of Iran's ports is set to begin later today, with the US Central Command confirming that the operation will commence at 10am ET, as tensions in the Middle East continue to escalate.

The blockade, which will target the Strait of Hormuz, a crucial waterway for international oil trade, is the latest development in the ongoing crisis between the US and Iran. The US president has made it clear that he is not interested in pursuing further talks with Iran, stating that he doesn't care if they come back to the negotiating table or not. This stance has raised concerns about the potential consequences of the blockade, including the impact on global oil prices and the risk of further conflict in the region. The US has been building up its military presence in the region in recent weeks, with a number of warships and aircraft deployed to the area.

The current crisis is part of a broader pattern of tensions between the US and Iran, which have been escalating for several years. The US withdrawal from the Iran nuclear deal in 2018 marked a significant turning point in the relationship between the two countries, and since then there have been numerous incidents of confrontation and retaliation. The blockade of the Strait of Hormuz is a major escalation of this conflict, and it has the potential to have far-reaching consequences for the global economy and regional stability. The strait is a vital waterway for international trade, with a significant proportion of the world's oil passing through it every day. Any disruption to shipping in the area could have a major impact on global oil prices and the economies of countries that rely heavily on oil imports.

The reaction to the US announcement has been swift, with many countries and international organisations expressing concern about the potential consequences of the blockade. The US move is likely to be seen as a provocative act by Iran and its allies, and it could lead to further retaliation and escalation of the conflict. The US has said that it is taking the action to protect its interests and those of its allies in the region, but the move is likely to be widely criticised as an unnecessary and dangerous escalation of the crisis. The next steps in the crisis are uncertain, but it is clear that the situation is highly volatile and that the risk of further conflict is high. The international community will be watching the situation closely, and there will be calls for calm and restraint from all parties involved.
