The war began with US and Israeli attacks on February 28, prompting Iran to attack Israel and US targets and allies in the Gulf.

In June, the United States and Iran signed a ceasefire agreement, intended to facilitate talks to end it.

Earlier this week, three commercial oil tankers were attacked as they attempted to cross a US-recommended route through Omani waters. Iran has repeatedly said the only “safe” route is a separate route through its waters.

The incident sparked a series of U.S. strikes that killed 17 people and wounded 115, according to Iranian officials. Iran responded with attacks against US allies in the Gulf.

The exchange increased tensions and led Trump to declare the ceasefire over.

However, the US leader said talks would continue and mediators have attempted to revive the process.

U.S. officials say they have conveyed through mediators the demand that Iran publicly declare that the Strait of Hormuz, a vital international shipping route, is open and pledge to stop firing on commercial ships.

According to US media, Iran told US officials that the attacks on the oil tankers were a mistake and blamed an internal rebel group.
