Welcome to our continuing live coverage of the crisis in Iran.

Donald Trump says he has been assured that the killing of Iranian protesters has been halted, adding when asked about whether the threatened US military action was now off the table that he will “watch it and see”.

The president said at the White House that “very important sources on the other side” had now assured him that Iranian executions would not go ahead. “They’ve said the killing has stopped and the executions won’t take place,” Trump said. “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.”

Earlier, Iranian foreign minister Abbas Araghchi told Fox News that executions executions were not taking place and there would be “no hanging today or tomorrow”. “I’m confident that there is no plan for hanging.”

The family of Erfan Soltani, the first Iranian protester sentenced to death since the current unrest began, has been told his execution has been postponed.

Here are some of the other latest developments:

• Trump said Iranian opposition figure Reza Pahlavi “seems very nice” but expressed uncertainty about whether Pahlavi would be able to muster support within Iran to eventually take over. “I don’t know how he’d play within his own country,” Trump told Reuters in the Oval Office. “And we really aren’t up to that point yet. I don’t know whether or not his country would accept his leadership, and certainly if they would, that would be fine with me.”

• Iran has reopened its airspace after a near-five-hour closure that forced airlines to cancel, reroute or delay some flights.

• The United Nations security council is scheduled to meet on Thursday afternoon for “a briefing on the situation in Iran”, according to a spokesperson for the Somali presidency. The scheduling note said the briefing was requested by the US.

• Some US and UK personnel have been evacuated as a precaution from sites in the Middle East. The British embassy in Tehran has also been temporarily closed.

• Spain, Italy and Poland advised their citizens to leave Iran. It followed a call by the US urging its citizens to leave Iran, suggesting land routes to Turkey or Armenia.

• Araghchi insisted the situation was “under control” and urged the US to engage in diplomacy. “Now there’s calm,” the Iranian foreign minister said. “We have everything under control, and let’s hope that wisdom prevails and we don’t end up in a situation of high tension that would be catastrophic for everyone.”

• The death toll in Iran from the regime’s crackdown stands at 2,571 people, according to the US-based Human Rights Activists news agency. More than 18,100 have been arrested, it said.

• Foreign ministers from the G7 group said they were “prepared to impose additional restrictive measures” on Iran over its handling of the protests, and the “deliberate use of violence, the killing of protesters, arbitrary detention and intimidation tactics”.
