Iran’s president Hassan Rouhani has branded the White House ‘mentally retarded’ after Donald Trump issued fresh sanctions against the leadership in Tehran.

Rouhani said the move proves that America is lying about wanting to negotiate and only proves that Washington is desperate and running out of options.

Speaking to a session of ministers that was broadcast on TV, Rouhani added that the new sanctions are ‘outrageous and idiotic’ and will fail because Ayatollah Khamenei – one of the main targets – has no foreign assets.

Trump imposed the sanctions Monday after Iran shot down a US spy drone which it claimed violated its airspace last week. America says the drone was in international airspace and the attack was ‘unprovoked’.
