US President Donald Trump warned of hitting Iran 'even harder' despite reports suggesting a peace deal between Washington and Tehran is imminent.
Trump made the remarks as a report in Al Arabiya suggested efforts were underway to finalise the text of an agreement, with completion expected within the next few hours.
Trump said talks with Iran were in the final stage, but warned of more attacks if Tehran did not agree to a deal.
Around the same time, Pakistan's army chief Field Marshal Asim Munir was reportedly set to travel to Iran to announce the final version of the agreement.
The developments come as the Middle East war set off by US's Operation Epic Fury nears its three-month completion.
The war has been paused since April 8 after a Pakistan-mediated ceasefire, but diplomatic efforts to end the skirmishes have been moving at a sluggish pace.
