The U.S. military on Monday denied claims that Iran struck a navy vessel as U.S. forces now offer to guide commercial ships through the Strait of Hormuz, where hundreds have been stuck since the Iran war began.

Iran's top negotiator warns that "we are just getting started" after the US and Iran launched attacks in the Strait of Hormuz on Monday. US Defence Secretary Pete Hegseth says the ceasefire "is not over".

Iran's military warned U.S. forces on Monday not to enter the Strait of Hormuz after President Donald Trump said the United States would start helping to free ships stranded in the Gulf.

Tensions seem to be escalating in the Middle East after the United States and Iran exchanged gunfire in the Strait of Hormuz.

The ceasefire in the Middle East was in peril Tuesday after the United States and Iran traded fire and threats over President Donald Trump's new mission to force open the Strait of Hormuz.

The U.S. military said it fired on Iranian forces and sank six small boats targeting civilian ships as it moved to reopen the Strait of Hormuz on Monday.

The U.S. military is rejecting claims that Iran struck a U.S. Navy vessel.

The U.S. used attack helicopters to blow up the small boats and intercept the drones, according to the commander of U.S. Central Command.
