Tehran enforces 'strict management' of the Strait of Hormuz as President Trump warns against attempted 'blackmail' through maritime blockades.

Tensions in the Persian Gulf escalated significantly over the last 24 hours as Iranian military forces fired warning shots at a British-flagged tanker and issued a formal blockade of the Strait of Hormuz. The Iranian Navy and Revolutionary Guards have placed the strategic waterway under "strict management and control," warning that any non-compliant commercial vessels will be treated as enemy collaborators. This sudden re-closure follows a brief reopening on Friday, causing immediate volatility in global energy markets as ships abandoned planned transits through the corridor, which handles 20% of the world’s oil and LNG supply. On the diplomatic front, the rhetoric remains mixed. U.S. President Donald Trump acknowledged that "very good conversations" are occurring but characterized Iran's latest maritime actions as an attempt to "blackmail" the United States. Meanwhile, Iranian Parliament Speaker Mohammad Bagher Ghalibaf noted that while discussions are moving forward, major gaps persist and a final resolution is not yet imminent. Analysts suggest the rapid reversal in Hormuz reflects internal pressures within Tehran as it navigates a fluid strategic environment involving Washington, Israel, and regional proxies.
