Shipping traffic in the Strait of Hormuz faces renewed disruption as at least eight vessels abruptly U-turned along the Omani coast, with several diverting to routes designated by Iran. While a mid-June US-Iran agreement sought to reopen the waterway, Tehran continues to assert control and warn against foreign military presence. In response, France and the UK are deploying naval assets and partnering with Oman to secure safe passage, highlighting deep geopolitical friction over the vital oil corridor.
