The US claimed the test violated UN Security Council Resolution 2231 which called on Iran “not to undertake any activity related to ballistic missiles.” Flynn said that the Trump administration “condemns such actions by Iran,” and has “officially put Iran on notice.“

Addressing the crowds on Friday, Iran’s President Hassan Rouhani also called on Iranians to “show their unbreakable ties with the Supreme Leader and the Islamic Republic.”

“Some inexperienced figures in the region and America are threatening Iran […] They should know that the language of threats has never worked with Iran […] They should learn to respect Iran and Iranians […] We will strongly confront any warmongering policies,” Rouhani told the crowd at the Azadi Square, as cited by Reuters, which reported that millions had shown up to commemorate the occasion across the country. At the Tehran rallies Friday, demonstrators chanted traditional slogans against the United States and Israel, and later, hundreds of thousands marched toward the city’s central Azadi Square, where Rouhani addressed the crowds, telling them that Iran will strongly answer any threat from its enemies. “We are united before bullying and any threat.”

On the anniversary of Iran’s 1979 Islamic Revolution that toppled the U.S.-backed Shah Mohammad Reza Pahlavi, marchers including hundreds of military personnel and policemen streamed towards Tehran’s Azadi (Freedom) Square for the main event. Another demonstrator in Tehran carried a small placard that read — in Farsi — “Trump, thank you for all your stupidities.”

At the rally, which culminated at Tehran’s Azadi (or Freedom) Square, a loudspeaker called for “tit-for-tat diplomacy.” But Iran has not taken steps to bar American travelers, making a show of offering visas to a U.S. freestyle wrestling team to allow it to participate in an international tournament next week. Earlier in February, the US also imposed new sanctions on Iran in response to a ballistic missile test, which Trump’s National Security Advisor Mike Flynn described as provocative and destabilizes the situation across the Middle East. Many ranking officials attended the ceremony in Tehran, including Gen. Qassem Soleimani who heads the Iranian Revolutionary Guard’s Quds Force, which focuses on foreign operations such as the war in Syria and Iraq’s fight against the Islamic State group where the Shiite power Iran supports Iraq’s government.
Iran marks its 38th anniversary of the Iranian Revolution with nationwide rallies and ceremonies. The ceremony also contains some anti-Trump protests.
