Conflict appears to have reached impasse, but leaders in Tehran and Washington seem to think victory is near

The month-old ceasefire between Iran and the US appeared to be in new peril on Tuesday with a fresh barrage of Iranian missiles reported to have targeted the United Arab Emirates as US naval forces pressed ahead with efforts to reopen the strait of Hormuz.

The Iranian strike on the UAE was the second in 48 hours, and came shortly after the US defence secretary, Pete Hegseth, insisted the shaky truce that has paused the war in the Middle East was intact, despite the new increase in violence.
