Three cargo ships have been targeted, and two seized, during passage through the Strait of Hormuz, as Iran issued the US a stark warning that the agreed ceasefire means "nothing".
Iran's Islamic Revolutionary Guard Corps intercepted the third ship, Panama-flagged vessel MSC Francesca, approximately six nautical miles from Iranian waters as it sailed southward towards the Gulf of Oman.
The IRGC contacted the vessel and "instructed to drop anchor", according to maritime intelligence company Vanguard
Crew members have since reported sustaining "damage to the hull and accommodation", though additional details remain unavailable at this time.

The UK Maritime Trade Operations has confirmed that the IRGC opened fire on the first vessel, with reports indicating Iran the IRGC also hit the other two ships.

UK Maritime Trade Operations confirmed crews aboard the vessels were safe and accounted for.
Following the stoppage, two of the three container vessels, Francesca and Epaminondas, were seized in Strait of Hormuz and transported to the Iranian coast.
The IRGC Navy Command wrote: "Two offending vessels had endangered maritime security by operating without the required permits and tampering with navigation systems, and were seized by the IRGC Navy and escorted to the Iranian coast."
LATEST DEVELOPMENTS
Nour News, affiliated with Iran's Supreme National Security Council, disputes an account given by the master of the ship to the UKMTO that no radio warning was given to the vessel.
Instead, it says the ship had "ignored warnings" from the Iranian armed forces.
Washington continues to enforce its naval blockade of the strategic waterway, a measure intended to exert pressure on Tehran ahead of planned diplomatic discussions in Pakistan.
The American president made his ceasefire extension announcement, whilst simultaneously maintaining the blockade, which restricts Iranian access to one of the world's most vital shipping lanes.
Significant doubt now surrounds the scheduled negotiations between the two nations.
Vice-President JD Vance failed to depart for Pakistan on Tuesday as had been anticipated, whilst Tehran has offered no formal reaction to the American president's statements.
An adviser to Iran's parliamentary speaker dismissed the gesture entirely, stating that the ceasefire extension "means nothing" and characterising it as "a ploy to buy time for a surprise strike".
