The United States on Jan. 15 said Iran halted 800 executions of protesters under pressure from 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 last 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 last 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 Jan. 15 that "all options remain on the table for the president".
"The president understands today that 800 executions that were scheduled and supposed to take place yesterday were halted," White House Press Secretary Karoline Leavitt told reporters.
She said Trump had warned Tehran of "grave consequences" if the killing of demonstrators continued.
The Treasury also announced new sanctions targeting Iranian officials on, with Tehran already under crippling restrictions over its nuclear program that contributed to the economic woes that sparked protests.
The Norway-based Iran Human Rights (IHR) NGO saidthat Iranian security forces had killed at least 3,428 protesters, warning that the final toll would be far higher.
Trump had said Wednesday he had received assurances from "very important sources on the other side" that executions would not go ahead.
With the belligerent rhetoric on all sides appearing to tone down for now, a senior Saudi official told AFP on that Saudi Arabia, Qatar and Oman led efforts to talk Trump out of an attack, fearing "grave blowbacks in the region.”
The Gulf trio "led a long, frantic, diplomatic last-minute effort to convince President Trump to give Iran a chance to show good intention,” the official said on condition of anonymity.
A second Gulf official confirmed the talks, adding that a message was also conveyed to Iran that attacking U.S. regional facilities would "have consequences.”
Asked about a New York Times report that Israeli Prime Minister Benjamin Netanyahu warned Trump against strikes, Leavitt said: "Look, it's true that the president spoke with [him], but I would never give details about their conversation without... the express approval by the president himself."
Iranian authorities have lashed out at "rioters" who they claim were backed by Israel and the U.S., vowing fast-track justice that activists fear will translate into a spree of executions.
