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.

Trump's tweet came as U.S. Secretary of State Mike Pompeo was headed to Saudi Arabia — four days after oilfields and a processing plant in the kingdom were attacked, an action American officialsbelieve originated from Iranian territory.
