**Iran War Live: IRGC Declares Strait of Hormuz Closed Over US Interference**

In a significant escalation of tensions in the Middle East, the Islamic Revolutionary Guard Corps (IRGC) of Iran has announced the closure of the Strait of Hormuz, a vital waterway for global oil shipments. This declaration comes amid ongoing military actions by Israel in Gaza and Lebanon, which have resulted in numerous civilian casualties.

The Strait of Hormuz, which connects the Persian Gulf to the Arabian Sea, is a crucial passage for approximately one-fifth of the world’s oil supply. The IRGC's announcement signals a potential disruption to international shipping routes, raising concerns among global markets and governments about the implications for energy security.

The closure is reportedly a response to what Iran perceives as increasing interference from the United States in the region. The US has maintained a military presence in the Persian Gulf, often citing the need to ensure the free flow of commerce and to counteract Iranian influence. The IRGC's move may be seen as a direct challenge to US authority in the area, as well as a demonstration of Iran's willingness to assert its control over strategic maritime routes.

This development occurs against a backdrop of heightened violence in the region, particularly as Israel intensifies its military operations against targets in Gaza and Lebanon. Reports indicate that these attacks have led to significant casualties among civilians, further inflaming tensions and drawing international condemnation.

The situation remains fluid, with potential ramifications for regional stability and global oil markets. Analysts warn that the closure of the Strait of Hormuz could lead to increased shipping costs and volatility in oil prices, as countries seek alternative routes for their energy supplies.

As the conflict continues to unfold, the international community is closely monitoring the situation, with calls for de-escalation and dialogue becoming increasingly urgent. The IRGC's declaration marks a pivotal moment in the ongoing tensions in the Middle East, highlighting the interconnected nature of regional conflicts and global security concerns.
