“I have just instructed the Secretary of the Treasury to substantially increase Sanctions on the country of Iran!” Trump tweeted Wednesday.

President Donald Trump on Wednesday pledged to “substantially increase” sanctions on Iran as tensions in the Middle East continue to rise following an attack on a Saudi oil field.

“I have just instructed the Secretary of the Treasury to substantially increase Sanctions on the country of Iran!” Trump tweeted.

Trump’s tweet came as U.S. Secretary of State Mike Pompeo was headed to Saudi Arabia to meet with Crown Prince Mohammed bin Salman to discuss the recent attack on the kingdom’s oil facilities, an action American officials believe originated from Iranian territory.

Later Wednesday, Trump told reporters in Los Angeles that his administration will “be adding some very significant sanctions” on Iran within the next two days.

NBC News reported Tuesday that the administration was weighing a range of options to retaliate against Iran, including a cyberattack or physical strikes, U.S. officials briefed on recent deliberations said.
