WASHINGTON: The ​US and Iran have reached an agreement ‌on ‌a ​60-day ‌memorandum ⁠of ​understanding to extend ⁠the ceasefire and launch ⁠negotiations ‌on Iran’s ‌nuclear program, ​but ‌President ‌Donald Trump still needs ‌to give final approval, Axios ⁠reported ⁠on Thursday, citing two US officials.

Also on Thursday, Iran’s Revolutionary Guard said it had targeted a US air base after the US military carried ​out what a Washington official said were strikes targeting an Iranian drone operation near the Strait of Hormuz,

The escalation in hostilities highlighted threats to the tenuous ceasefire between the US and Iran that took effect in early April, dampening hopes for a peace deal and sending oil prices surging again.

The US official, who requested anonymity to speak candidly about military operations, told Reuters the military shot down four Iranian attack drones and struck a ground control station in the port city of Bandar Abbas that was about to launch a fifth drone.
