The Iranian Foreign Minister Abbas Araghchi has touched down in Geneva for high-stakes nuclear talks between the US and Iran.  

Mr Araghchi wrote on social media that he was in the Swiss city for "real ideas to achieve a fair and equitable deal", but he also added "what is not on the table: submission before threats".

US President Donald Trump has threatened further strikes against Tehran if a deal to curb the country's nuclear program can't be reached, with the US building up its military presence in the region.
