'Reckless, belligerent': Iran complains about Donald Trump's threat to UN

Iran on Monday complained to the United Nations Security Council about the "reckless and belligerent" remarks made by US President Donald Trump, Reuters reported.
Iran described Trump's comments as "a flagrant violation of international law" and the founding United Nations Charter.
In a letter seen by Reuters, Iran's UN Ambassador Amir Saeid Iravani wrote that Tehran "strongly warns against any military adventurism and will respond swiftly and decisively to any act of aggression or attack by the United States or its proxy, the Israeli regime, against its sovereignty, territorial integrity, or national interests."
This statement came a day after Trump threatened Iran with military action if Tehran does not agree to a new nuclear deal with Washington.
The threat was made during a phone interview with NBC News, where Trump stated that if Iran fails to make a deal, there would be "bombing the likes of which they have never seen before." Additionally, Trump mentioned the possibility of imposing secondary tariffs on Iran if an agreement is not reached.
Iranian Supreme Leader Ayatollah Ali Khamenei warned that if the US acts on Trump's threat, Iran will deliver a "strong blow" in retaliation. Iran has also prepared its missile arsenal, with many missiles positioned in underground facilities designed to withstand airstrikes, ready to strike US-linked positions worldwide.
Trump's threat came after Iran rejected direct negotiations with the US but said it was open to indirect talks through intermediaries like Oman. Tensions between the US and Iran have escalated significantly since Trump withdrew from the 2015 Joint Comprehensive Plan of Action (JCPOA), also known as the Iran nuclear deal, during his first term in office.
