Trump says Rouhani "better be careful"

US president Donald Trump has reacted to his Iranian counterpart who has said that Tehran will never yield to the language of threats.

Trump says Iran's president had “better be careful” about his words. Hassan Rouhani said on Friday that Tehran will strongly respond to any move by ill-wishers. Since he took office last month, the US president has adopted a hostile policy toward Iran. He has slapped new sanctions and put Iranians on an immigration ban. Trump has also said Iran has been formally “put on notice” over its ballistic missile test.
