US and Iranian officials are due to meet in Geneva on Thursday for a third round of indirect talks, as President Donald Trump threatens to strike Iran if a nuclear deal is not reached, the BBC reports.
The discussions come amid the largest US military build-up in the Middle East since the US-led invasion of Iraq in 2003, and with Iran vowing to respond to an attack with force.
The talks are seen as a last-ditch effort to prevent a conflict, but the chances of an agreement remain unclear.
While Trump has said he prefers to solve the crisis through diplomacy, he has also said he is considering a limited strike on Iran to pressure its leaders to accept a deal.
