The United States on Thursday said Iran halted 800 executions of protesters under pressure from US President Donald Trump, after Gulf allies appeared to pull him back from military action over Tehran’s deadly crackdown on demonstrations.

Iran was shaken over the past week by some of the biggest anti-government protests in the history of the Islamic Republic, although the demonstrations appear to have diminished over the past few days in the face of repression and a week-long internet blackout.

While Washington has stepped back from military action, the White House said on Thursday that “all options remain on the table for the president”.
