President Donald Trump has tried to preserve an increasingly fragile interim deal as hostilities have mounted in recent days in the Strait of Hormuz

A fragile truce between Iran and the United States appeared increasingly shaky early on June 28 as both sides accused one another of violating an interim agreement meant to halt months of fighting, amid renewed missile, drone, and air strikes across the Gulf region.

The United States and Iran have agreed to suspend ongoing military strikes and move toward high-level negotiations in Qatar on Tuesday, in what officials describe as an urgent attempt to stabilize the situation around the Strait of Hormuz after days of escalating confrontation. The agreement was reported by US media outlets, citing senior American officials, and follows a weekend of tit-for-tat attacks that put an interim understanding signed on 17 June under severe strain.

During negotiations in Switzerland a week ago, the U.S. delegation agreed with Iran to establish a "hotline" between the U.S. military and Iran's Islamic Revolution Guard Corps to coordinate traffic in the strait.
