We're recording this at 15 hours GMT on Friday the 1st of May.
The deadline has passed for the Trump administration to get approval for the war on Iran,
even as the president is briefed on new military options.
Ukraine hits oil facilities in a Russian Black Sea port for the fourth time in two weeks.
And one of the world's largest manufacturers of fertilizer warns of serious disruption to food supplies.
Also in the podcast, from a British couple detained in Iran.
