US President Donald Trump has defended his decision to withdraw troops from north-eastern Syria and threatened to "totally destroy and obliterate" the Turkish economy.
It comes amid fears the remaining Kurdish forces in Syria will be vulnerable to an attack by Turkey.
Mr Trump took to Twitter to issue the warning, as even staunch Republican congressional allies condemned the move.
"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 (I've done before!)," he wrote.

A former United States military chief, General David Petraeus, has since criticised the call - saying it raises concerns about America's "level of commitment" to partners and allies.
The Kurdish forces who fought alongside the US against so-called Islamic State, but are considered terrorists by Turkey, still remain in the region - prompting some to suggest they have been abandoned by their US ally.
Senior House Republican Liz Cheney called the move "a catastrophic mistake", while Republican Senator Lindsey Graham labelled the decision a "shot in the arm to the bad guys".
Mr Trump added that he had told Turkey they "could suffer the wrath of an extremely decimated economy" if the nation does "anything outside of what we would think is humane."
The chairman of the Foreign Affairs Committee, Tom Tugendhat, said the "surprise withdrawal" of US troops could trigger a humanitarian crisis - urging all parties involved to protect the civilians in the region.
"We urge Turkey and the US to work together to establish mechanisms to prevent any further military escalation", he said.
