The fragile ceasefire between the US and Iran is under threat after a drone attack targeted a cargo ship in the Strait of Hormuz, prompting a US military response.
The latest escalation marks the most serious test of an interim agreement reached just a week ago, aimed at ending months of conflict and restoring stability in the strategically vital shipping corridor.
US President Donald Trump said the attack amounted to a violation of the ceasefire, while Iran rejected the claim, saying it was 'ceasefire management'.
The dispute centres on navigation rules in the Strait of Hormuz, with Iran insisting that vessels travel only through Tehran-approved corridors.
Despite Thursday's drone attack, more than two dozen ships continued to use the southern route through the strait on Friday, while at least two tankers reportedly turned back after Iran's insistence.
