Donald Trump issued an expletive-laden warning on Sunday that Tehran had until Tuesday night to reopen the strait of Hormuz or the US would obliterate Iran’s power plants and bridges.

Iran’s parliament speaker responded with a warning that the US president’s “reckless moves” would mean “our whole region is going to burn”.

The latest threat of escalation in the five-week war followed the rescue of a second crew member of a downed F-15E fighter by US commandos, ending a two-day search after the warplane crashed in south-west Iran.
