US President Donald Trump has said he is considering a limited military strike on Iran in order to pressure its leaders to agree a deal to curb the nuclear programme.
The president made the remark in response to a question from a journalist hours after officials had suggested the possibility of a strike.
On Thursday, Trump said the world would find out "over the next, probably, 10 days" whether a deal would be reached or the US would take military action. The US has been increasing its military presence in the region in recent weeks.
The US and its European allies suspect that Iran is moving towards the development of a nuclear weapon, something Iran has always denied.
US and Iranian officials have met over the issue in Switzerland and said progress has been made in the talks.
