US President Donald Trump said Wednesday he had been told the killings of protesters in Iran had been halted, but added that he would "watch it and see" about threatened military action.
Trump had repeatedly talked in recent days about coming to the aid of the Iranian people over the crackdown on protests that rights groups say has left at least 3,428 people dead, AFP said.
But in a surprise announcement at the White House, Trump said he had now received assurances from "very important sources on the other side" that Tehran had now stopped, and that executions would not go ahead.
"They've said the killing has stopped and the executions won't take place -- there were supposed to be a lot of executions today and that the executions won't take place -- and we're going to find out," Trump said.
He offered no details and noted that the United States had yet to verify the claims.
Asked by an AFP reporter in the Oval Office if US military action was now off the table, Trump replied: "We're going to watch it and see what the process is."
Iranian Foreign Minister Abbas Araghchi later said there would be "no hanging today or tomorrow," in an interview with US network Fox News, while accusing Israel of orchestrating violence, without providing evidence.
Araghchi contends the peaceful protests about economic hardship that began December 28 devolved into widespread violence between January 7 and 10 because the protests were infiltrated by external "elements who had a plan to create a big number of killings in order to provoke President Trump to enter into this conflict and start a new war against Iran."
Iran's Minister of Justice Amin Hossein Rahimi echoed that allegation, telling state news agencies that after January 7, "those weren't protests any longer" and anyone who was arrested on the streets then "was definitely a criminal."
A rights group said separately that the execution of an Iranian man arrested during the wave of protests, 26-year-old Erfan Soltani, would not take place as scheduled on Wednesday, citing relatives.
Late Wednesday, UN leadership announced a meeting of the Security Council Thursday for "a briefing on the situation in Iran," as requested by the United States.
Trump's comments sent oil prices plunging on Thursday morning, as concerns eased of a looming supply shock in energy markets. Iran makes up around three percent of global oil production.
- 'Full control' -
Araghchi said the Iranian government was "in full control" and reported an atmosphere of "calm" after what he called three days of "terrorist operation."
Iran also struck a defiant tone about responding to any US attack, as Washington appeared to draw down staff at a base in Qatar that Tehran targeted in a strike last year.
Iran targeted the Al Udeid base in June in retaliation for US strikes on its nuclear facilities. Ali Shamkhani, a senior advisor to Supreme Leader Ali Khamenei, warned Trump the strike showed "Iran's will and capability to respond to any attack."
Fears of possible US military action continued to rile the region.
The British government said its embassy in Tehran had been "temporarily closed," India's government urged its citizens to leave the country.
Germany's Lufthansa on Wednesday said its flights would avoid Iranian and Iraqi airspace "until further notice" after the US threats against Iran.
Trump has threatened to intervene militarily in Iran several times since the protest movement that has shaken the country began in late December. The protests are the largest since the Iranian Republic was proclaimed in 1979.
Rights monitors say that under cover of a five-day internet blackout, Iranian authorities are carrying out their harshest repression in years against demonstrations openly challenging the theocratic system.
Iran's judiciary chief vowed fast-track trials for those arrested, stoking fears authorities will use capital punishment as a tool of repression.
In Tehran, authorities held a funeral for more than 100 security personnel and other "martyrs" killed in the unrest, which officials have branded "acts of terror."
- 'Unprecedented level of brutality' -
G7 nations said Wednesday they were "deeply alarmed at the high level of reported deaths and injuries" and warned of further sanctions if the crackdown continued.
Monitor NetBlocks said Iran's internet blackout had lasted 144 hours. Despite the shutdown, new videos, with locations verified by AFP, showed bodies lined up in the Kahrizak morgue south of Tehran, wrapped in black bags as distraught relatives searched for loved ones.
The US-based Institute for the Study of War said authorities were using "an unprecedented level of brutality to suppress protests," noting reports of protest activity had sharply declined.
A senior Iranian official told journalists there had been no new "riots" since Monday, distinguishing them from earlier cost-of-living protests. "Every society can expect protests, but we will not tolerate violence," he said.
Prosecutors have said some detainees will face capital charges of "waging war against God." State media reported hundreds of arrests and the detention of a foreign national for espionage, without giving details.
Iran Human Rights, based in Norway, said security forces had killed at least 3,428 protesters and arrested more than 10,000.
