US President Donald Trump has announced that Turkey will be ending its military offensive into Syria, making a US-brokered ceasefire "permanent".
Speaking at the White House, Mr Trump said Turkey had informed his administration that it would be "stopping combat and their offensive in Syria" and "making the ceasefire permanent."
Mr Trump said the US is taking credit for the events, which also followed a deal between Turkey and Russia to remove Kurdish forces for the border.
Turkey considers the Kurdish-led Syrian Democratic Forces terrorists, launching a cross-border offensive into northern Syria after the withdrawal of US forces from the region earlier this month.
The US fought against the Islamic State group (IS) alongside the Kurds, before leaving them behind.
"This was an outcome created by us, the United States, and nobody else," said Mr Trump, in reference to the news Syria will no longer continue the assault.
Turkey's deal will Russian leader Vladimir Putin came hours before the end to the 120-hour, US-brokered ceasefire.
Turkey had intended to resume attacks without a Kurdish retreat.
Under the deal, Russian military police would patrol the northern border in Syria, Kurdish fighters who fought were given 150 hours to withdraw 30 kilometres from the boundary with Turkey, from midday on Wednesday.
Mr Trump mentioned the instability of peace in Syria, but said he believes the ceasefire is set in stone: "You would also define the word 'permanent' in that part of the world as somewhat questionable, we all understand that. But I do believe it will be permanent," he said.
Sanctions imposed on Turkey by the US whilst the offensive was taking place have now been lifted, Trump also announced.
The destination of the American troops evacuating is also being considered, plans to move some forces to Iraq disturbed by the Iraqi military, who say the US can only move there in transit and cannot stay.
