TEHRAN, MAY 30: Mohsen Rezaei, an adviser to Iran’s Supreme Leader Mojtaba Khamenei, said on Saturday that US President Donald Trump was “betraying diplomacy for the third time” by continuing a naval blockade imposed on Iran and making what he described as excessive demands in negotiations.

The United States warned it was “more than capable” of resuming war with Iran after Trump said any peace deal must adhere to his red lines, including Tehran never being able to develop nuclear weapons.

The White House had signaled Trump was close to a decision on an initial deal after weeks of mixed signals in tenuous negotiations, though Tehran denied there was a final agreement on ending the Middle East conflict that has jolted the global economy.
