Turkey's battered lira weakened 5 percent on Friday after a Turkish court rejected an American pastor's appeal for release, drawing a stiff rebuke from President Donald Trump who said the United States would not take the detention "sitting down".
He said: "We put sanctions on several cabinet members".
Mr. Trump wrote in a tweet late Thursday: "We will pay nothing for the release of an innocent man, but we are cutting back on Turkey!" They came out. They want to hold our wonderful pastor.
That move was followed by an announcement by Trump last week that the United States was doubling tariffs on imported Turkish metals.

Erdogan has said Turkey is the target of an economic war, and has made repeated calls for Turks to sell their dollars and euros to shore up the currency.
A day earlier, he said the U.S. was seeking to stab Turkey "in the back" by sending the lira into a tailspin.
"You act on one side as a strategic partner but on the other you fire bullets into the foot of your strategic partner", Erdogan said.
