Iran's retaliation came immediately after the US President Donald Trump has declared Iranian Revolution Guards Corps [IRGC] as a "terrorist group".

Iran’s Supreme National Security Council put US forces in West Asia, known as the United States Central Command [CENTCOM], on its terror list.

The decision was announced by Iranian state television.

Washington's decision does not coincide with international law and is therefore not legal or legitimate said state-run TV in the announcement.

In a statement later in the day, Iran’s Supreme National Security Council said it has put CENTCOM on its terror list as a "reciprocal measure" against US President Donald Trump's "illegal and unwise" move to blacklist IRGC a foreign terrorist organization.

"Iran regards this baseless move as a major threat to regional and international peace and security and a blatant violation of the compelling rules of international law and the United Nations Charter," it added.

The top security council said that CENTCOM has been tasked with implementing terrorist policies of the US government against countries in West Asia, noting that CENTCOM’s effort to impose those policies has endangered Iran's national security and the lives of both Iranians and non-Iranians, including through participation of the US in the massacre of the Yemeni people and other civilians in the West Asia region.

Iranian Foreign Minister Mohammad Javad Zarif on Monday proposed that the SNSC should add American forces in West Asia to its list of terrorist groups.

The Iranian Foreign Ministry also issued a diplomatic note to the United States for blacklisting revolutionary guards as a "terrorist organizations". (ILKHA)
