He repeated the White House line that 800 executions that were scheduled and supposed to take place yesterday were halted in Iran. He even 'thanked' the Iranians for not carry out the supposed mass execution plan:

"I greatly respect the fact that all scheduled hangings, which were to take place yesterday (Over 800 of them), have been cancelled by the leadership of Iran. Thank you!" he wrote earlier in the day.

He also told reporters "I convinced my myself" not to attack Iran, after painting himself in a corner by essentially setting red lines previously. Trump had said days ago if Iranian authorities kill protesters they would get hit hard by the US.

As for the "800 executions" - it's very unclear where this number came from. Certainly Iranian state media or officials haven't said any such thing, and there's a likelihood it's just propaganda. 

US Ambassador to the United Nations Mike Waltz told the UN Security Council on Thursday that the "brave people of Iran" have risen up and that President Donald Trump "has made it clear all options are on the table to stop the slaughter" - this despite widespread reports that the protests and rioting are over at this point.

"President Trump is a man of action, not endless talk like we see at the United Nations. He has made it clear all options are on the table to stop the slaughter," Waltz told the Security Council meeting, held at the request of Washington.

"Everyone in the world needs to know that the regime is weaker than ever before, and therefore is putting forward this lie because of the power of the Iranian people in the streets. They are afraid. They're afraid of their own people," Waltz claimed, but he did not address the huge pro-government rallies which engulfed Iranian streets from earlier this week, which largely supplanted the protests and riots.

But a near total internet outage has endured going all the way back to January 8. This suggests the crisis may not be completely finished, but Tehran is touting that security services and police are back in control of the streets.

The US is still rushing military assets to the area. "The Pentagon is moving a carrier strike group from the South China Sea to the U.S. Central Command area of responsibility, which includes the Middle East, as tensions escalate between the Trump administration and Iran," according to NewsNation.

"Moving the carrier strike group - a naval formation centering around an aircraft carrier, with a variety of other vessels, including at least one attack submarine - is expected to take about a week, a source said," the report continues. "The USS Abraham Lincoln reportedly is the aircraft carrier that is on the move."
