WATCH: Trump White House 'Officially' Puts Iran 'On Notice'

At the WH press briefing today, press sec Sean Spicer hands the podium to Trump National Security Adviser Mike Flynn, who puts Iran on notice for their actions. Long overdue.

WASHINGTON, Feb 1 (Reuters) - A top adviser to President Trump delivered a tough warning to Iran for test-firing a ballistic missile and declared "we are officially putting Iran on notice" for what he called a provocation.

A statement from White House national security adviser Michael Flynn condemning the test was an example of a more muscular U.S. foreign policy that Trump has said he would pursue.

Iran confirmed on Wednesday it had tested a new missile but said it did not breach a nuclear accord reached with world powers or a U.N. Security Council resolution that endorsed the pact. Flynn said the missile launch violated the 2015 security council resolution.

The Islamic Republic has test-fired several ballistic missiles since the nuclear deal in 2015, but the latest test was the first since Trump took office last month.

Flynn said the missile launch and an attack against a Saudi naval vessel by Iran-allied Houthi militants off the coast of Yemen underscored "Iran's destabilizing behavior across the Middle East."
