President Donald Trump has threatened to destroy Turkey's economy if Turkey goes "off limits" after his decision to pull US forces out of north-eastern Syria.
In a series of tweets, Mr Trump defended his move that could open the way for Turkey to launch an attack on Kurdish fighters across the border.
The withdrawal was heavily criticised even by Mr Trump's Republican allies.
Kurdish forces were key US allies in defeating the Islamic State in Syria.
Mr Trump's surprise move – described by the main Kurdish-led group as a "stab in the back" – goes against the advice of senior officials in the Pentagon and state department.
Critics say the withdrawal could facilitate an IS resurgence and leave Kurdish forces at risk of being attacked by Turkey, which regards them as terrorists. But Mr Trump warned Turkey not to take advantage of his decision, saying he could "destroy and obliterate" its economy.

As I have stated strongly before, and just to reiterate, if Turkey does anything that I, in my great and unmatched wisdom, consider to be off limits, I will totally destroy and obliterate the Economy of Turkey (Ive done before!). They must, with Europe and others, watch over…

Last year, the US raised tariffs on some Turkish products and imposed sanctions on top officials as relations between the two Nato countries worsened over a number of issues.
Turkish President Recep Tayyip Erdogan has said his aim is to combat Kurdish fighters in the border area and set up a "safe zone" for up to two million of the more than 3.6 million Syrian refugees currently living in Turkey.
In a statement, Pentagon spokesman Jonathan Hoffman said "the Department of Defense made clear to Turkey – as did the president – that we do not endorse a Turkish operation in Northern Syria".
Earlier, Mr Trump said it was time "to get out of these ridiculous Endless Wars, many of them tribal" and that "Turkey, Europe, Syria, Iran, Iraq, Russia and the Kurds will now have to figure the situation out".
'Disaster in the making'
US Republican Senator Lindsey Graham, a close ally of the president, was among those who criticised the decision. Calling the move a "disaster in the making", Mr Graham said he would introduce a Senate resolution opposing the decision and calling for it to be reversed.
"I hope President Trump will reassess and take sound military advice," he wrote on Twitter. "We have sent the most dangerous signal possible – America is an unreliable ally."
Nikki Haley, former US ambassador to the UN, said the Kurds "were instrumental in our successful fight against" IS in Syria and that "leaving them to die [was] a big mistake".
In other reaction:
- Kino Gabriel, spokesman for the Kurdish-led Syrian Democratic Forces (SDF) – which occupy former IS territory in north-eastern Syria – told Arabic TV station al-Hadath that the move "was a surprise and we can say that it is a stab in the back for the SDF"
- Brett McGurk, former US special presidential envoy for the coalition against IS, said the announcement demonstrated a "complete lack of understanding of anything happening on the ground"
- UN humanitarian chief in Syria Panos Moumtzis said aid workers were "preparing for the worst" if fighting breaks out in north-eastern Syria
Speaking to reporters, a senior state department official said the number of personnel being pulled back from the border area was "very small", and that they had been moved a "very short distance".
Dysfunctional foreign policy
In the place of clarity we only have President Trump's tweets and statements which appear to contradict him from both the state department and the Pentagon. This morning he appeared to signal the start of a US troop pullout from Syria and seemed to be washing his hands of the country, implicitly giving a green light for a major Turkish incursRead More – Source
