Hello and welcome to NewsHour.
It's coming to you live from the BBC World Service studios in central London.
I'm Tim Franks.
And we 're beginning with the war in Iran, where the landscape is shifting, with shifting deadlines,
shifting objectives and rhetoric, which over the weekend shifted to a new sweary pitch.
On that point, if you did n't hear or read it,
this was President Trump's profanity-strewn post on social media on Easter Sunday,
in which he announced that tomorrow, Tuesday, will be, as he put it.
Power plant day and bridge day all wrapped up in one.
An implicit but pretty clear threat that major civilian infrastructure would be targeted deliberately by US forces.
Unless, that is, Iran release its chokehold on the Strait of Hormuz.
I would quote the rest of his post, but given its sweariness,
it would probably be my last day in broadcasting, at least for the BBC World Service.
Iran, for its part, has warned that its response to any such strikes would be much more devastating
and widespread than it has staged so far.
There is also, of course, a wider question as to whether the deliberate destruction of energy
and transport infrastructure would amount to war crimes.
Let's begin, though, with some voices from inside Iran.
Communications can be patchy with a lot of disruption to the internet.
We did, though, get in touch with this businessman in Tehran.
