Iran vows retaliation over 'hostile' US sanctions

Iran has said that it will retaliate against the sanctions imposed by the United States on the head of its judiciary, Ayatollah Sadeq Amoli-Larijani.

Iran also refused to accept any changes to its 2015 nuclear deal with the world powers.

On Friday, U.S. President Donald Trump, a critic of the 2015 accord to prevent Iran developing nuclear arms, said that he would extend sanctions relief one last time to give Washington and its European allies a chance to fix the "terrible flaws".

However, the U.S. imposed fresh sanctions on 14 individuals and entities over alleged human rights abuses.

Iran's Foreign Ministry said in a statement carried by state media, "The Trump regime's hostile action (against Larijani) crossed all red lines of conduct in the international community and is a violation of international law and will surely be answered by a serious reaction of the Islamic Republic".

Iran's Foreign Minister Mohammad Javad Zarif had earlier said on Twitter that Trump's decision undermined the multilateral agreement.
