President Trump announced Tuesday that he has decided to exit a 2015 six-nation agreement in which Iran agreed to limit its production of nuclear weapons material.

"I am announcing today that the United States will withdraw from the Iran nuclear deal," Trump said.

He said the U.S. will re-impose economic sanctions that were lifted as part of the U.S. commitments made in the deal.

The U.S. has been repeatedly waiving sanctions that curtail Iran's oil sales but those sanctions waivers face a Saturday deadline, prompting Trump's move Tuesday.

He had been in power for a decade, and recent constitutional changes to boost the premier's authority had made the office an enticing way to retain that power while still observing term limits.
