Iran has warned that it could adopt a more aggressive military posture if diplomatic efforts with the United States fail, particularly over the Strait of Hormuz. A senior Iranian official said Tehran could take action to challenge the US naval blockade if Washington does not move toward implementing the interim agreement.
The warning comes as the 60-day US-Iran memorandum of understanding has expired, with negotiations for a longer-term settlement facing serious difficulties. US President Donald Trump has ruled out extending the temporary arrangement, while Washington continues to press Tehran over the reopening of the Strait of Hormuz.
The strategic waterway remains at the centre of the dispute because of its importance to global energy supplies. The latest developments have increased concerns about further regional instability and pressure on international oil markets.
