Middle East live: Iran warns against attempts to cross Strait of Hormuz without authorisation

Iran's Revolutionary Guards have issued a stern warning to any vessel attempting to navigate the Strait of Hormuz without authorization, signaling heightened tensions in the region. This comes amid US Senator Marco Rubio's visit to Bahrain, where he reassured Gulf allies of Washington's commitment to their security as it negotiates a final deal with Iran. The Strait of Hormuz is a critical global shipping route, and any disruption could have significant economic and geopolitical implications, affecting oil supplies and global trade. This escalation underscores the fragile state of US-Iran relations and the broader Middle East dynamics.
