President Donald Trump said on Monday the United States was in talks with a "more reasonable regime" to end the war in Iran but repeated his warning to Tehran to open the Strait of Hormuz or risk US attacks on its oil wells and power plants.
"Great progress has been made but, if for any reason a deal is not shortly reached, which it probably will be, and if the Hormuz Strait is not immediately 'Open for Business,' we will conclude our lovely 'stay' in Iran by... obliterating all of their Electric Generating Plants, Oil Wells and Kharg Island," Trump wrote in a social media post.
Trump also threatened to attack the desalination plants that supply clean water in Iran.
The US president said last week he would pause attacks on Iran's energy plants for 10 days, which would be until April 6, US time.
While Trump has said the US and Iran are making progress in talks, he has also been sending more US troops to the region, leading Iran's parliament speaker to accuse Washington of sending messages about possible negotiations while planning a ground invasion, prompting more defiance from Tehran.
Iranian leaders have denied being in direct talks with the US.
Iran said on Thursday it was reviewing Washington's latest position on ending the war after US President Donald Trump suggested he was prepared to wait a few days to "get the right answers" from Tehran but warned of renewed attacks if it did not agree to a deal.
