U.S. Treasury's Mnuchin says U.S. will ramp up pressure on Iran

Treasury Secretary Steven Mnuchin said on Monday the United States would increase economic pressure on Iran over its nuclear program, making the pledge during a Middle East trip that includes visits to U.S. allies Israel and Saudi Arabia. Sanctions reimposed on Tehran by President Donald Trump after he withdrew the United States from world powers' 2015 nuclear pact with Tehran have dried up Iranian oil revenues and cut Iranian banks’ ties to the financial world.
