After Iran test-launched a ballistic missile on Jan. 29, National Security Adviser Michael Flynn said the Middle-Eastern nation is now "on notice" for its "provocative" breach of a U.N. Security Council resolution.
"As of today, we are officially putting Iran on notice," Flynn said in a statement, according to a Facebook post by President Donald Trump.
Citing Iran's backing of Houthi rebels in Yemen, who are at odds with U.S. allies, and the nation's other "destabilizing behavior across the Middle East," Flynn said Tehran has become "emboldened" by the Obama administration's "weak and ineffective" approach.
"The Obama Administration failed to respond adequately to Tehran's malign actions -- including weapons transfers, support for terrorism and other violations of international norms," Flynn added. "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."
The national security adviser criticized Iran for continuing to "threaten U.S. friends and allies in the region," although Flynn did not specify what type of "notice" Iran has been put on or if the White House intends to pursue further action.
Three senior officials with the Trump administration told CNN that White House leaders are still discussing what their next move will be and whether it would entail economic sanctions, financial penalties, military action or a combination of the three.
"We are considering a whole range of options," one of the officials told CNN. "We're in a deliberative process."
The U.N. Security Council prohibits Iran from testing "ballistic missiles designed to be capable of delivering nuclear weapons," although Iran's foreign ministry said on Jan. 31 that it was not in violation of Resolution 2231, as the action was "solely for defensive purposes." Flynn said that the missile test was "in defiance" of the resolution.
