Iran has woken up to news that President Donald Trump plans to announce his decision about whether to pull America out of the nuclear deal between Tehran and with world powers.

Trump's tweet came late on Monday night, meaning major newspapers across Iran missed the announcement for their front pages.

Iran's state-run television broadcaster carried the announcement at 10 a.m. local time, and Iran's state-run IRNA news agency also carried a report on it.

Overnight, Iran's semi-official news agencies carried the news off Trump's tweet, while others shared foreign media reports online.

Trump's announcement, set for the 2 p.m. EST at the White House, will come after nightfall in Iran. Iranian officials offered no immediate reaction to Trump's upcoming decision.
