Israel says it has launched a âpreventativeâ strike on Iran and is preparing for retaliation.
On Friday, Donald Trump said he had not made a final decision on whether to launch US strikes on Iran â but added he was ânot happyâ with the situation, and that military force, including regime change, remained an option.
Talks between the US and Iran on Tehranâs nuclear programme ended inconclusively, with a suggestion that further discussions would be held next week.
It comes amid a massive buildup of US naval forces in the Middle East, including repositioning aircraft carriers and other warships.
Trump had previously given Tehran a deadline of 10 to 15 days to make a deal to resolve their longstanding nuclear dispute or face âreally bad thingsâ.
It came as Iran accused the US of spreading âbig liesâ about its missiles programme, after Trump claimed Tehran was building weapons that could strike the US.
During his State of the Union speech, the US president said Iran has âalready developed missiles that can threaten Europe and our bases overseas, and theyâre working to build missiles that will soon reachâ the US.
He described Iran as âthe worldâs number one sponsor of terrorâ and claimed at least 32,000 protesters were killed during recent unrest in the country.
Baqaei rejected those claims, without mentioning Trump directly. âWhatever theyâre alleging in regards to Iranâs nuclear programme, Iranâs ballistic missiles, and the number of casualties during Januaryâs unrest, is simply the repetition of âbig liesâ,â he posted on X.
