Michael Flynn, national security advisor for President Trump, made a statement Wednesday regarding Iran’s recent ballistic missile test, as well as attacks on Saudi naval vessels in the Red Sea. According to Flynn, these acts demonstrate Iran’s continued efforts to increase its aggressive influence within the Arab world.

“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,” Flynn said.

“Instead of being thankful to the United States for these agreements, Iran is now feeling emboldened,” Flynn continued. “As of today, we are officially putting Iran on notice.”

Flynn then pointed the finger at the Obama administration for failing to take action. “The Obama administration failed to respond adequately to Tehran’s malign actions, including weapons transfers, support for terrorism, and other violations of international norms.”

Sean Spicer, Trump’s press secretary, notified the press that a briefing from the National Security Council would soon follow.

Houthi rebels, believed to be backed by Iran, executed a suicide attack on a Saudi frigate on Monday. Initial reports indicated that the ship had been hit by a missile, but video footage suggests that a suicide bomber rammed a small boat into the side of the vessel. The ensuing explosion claimed the lives of two Saudi sailors and left three more injured.
