Iran's Supreme Leader Ayatollah Ali Khamenei on Wednesday rejected holding negotiations with the United States over a nuclear deal, as a letter was delivered from U.S. President Donald Trump calling for such talks.

The US president says he has proposed talks on a deal to prevent Iran acquiring nuclear weapons and to avert military action.

Iran’s Supreme Leader Ayatollah Ali Khamenei said his country is not pursuing nuclear weapons and dismissed US President Donald Trump’s calls for negotiations as a “trick.”
