President Trump's national security adviser announced Wednesday that the White House has officially put Iran "on notice" following reports that Iran has tested several ballistic missiles since reaching an agreement with the previous administration in 2015.

"We are official putting Iran on notice," Mike Flynn told reporters at the daily White House briefing.

White House press secretary Sean Spicer later added that the administration "wanted to make very clear that we felt that [Iran's] actions are both provocative and in violation [of the nuclear deal] and make sure they knew that we're not going to sit by and do nothing."

Flynn said Iran has demonstrated that it is "emboldened" by the controversial nuclear agreement, rather than "thankful" for the deal.

Members of the White House National Security Council are expected to brief reporters late Wednesday afternoon on actions the administration could take against Iran.

Flynn's entire statement is below:

"Recent Iranian actions, including a provocative ballistic missile launch and an attack against a Saudi naval vessel conducted by Iran-supported Houthi militants, underscore what should have been clear to the international community all along about Iran's destabilizing behavior across the Middle East.
The recent ballistic missile launch is also in defiance of UN Security Council Resolution 2231, which calls upon Iran "not to undertake any activity related to ballistic missiles designed to be capable of delivering nuclear weapons, including launches using such ballistic missile technology."
These are just the latest of a series of incidents in the past six months in which Houthi forces that Iran has trained and armed have struck Emirati and Saudi vessels, and threatened U.S. and allied vessels transiting the Red Sea. In these and other similar activities, Iran continues to threaten U.S. friends and allies in the region.
The Obama Administration failed to respond adequately to Tehran's malign actions — including weapons transfers, support for terrorism, and other violations of international norms. The Trump Administration condemns such actions by Iran that undermine security, prosperity, and stability throughout and beyond the Middle East and place American lives at risk.
President Trump has severely criticized the various agreements reached between Iran and the Obama Administration, as well as the United Nations – as being weak and ineffective.
Instead of being thankful to the United States for these agreements, Iran is now feeling emboldened.
As of today, we are officially putting Iran on notice."
