The killing of the Supreme Leader Ali Khamenei on Saturday, definitely dealing a blow to Iran's ruling structure.

And yet I think a lot of people are asking at this point if this is actually changing anything.

What can you say?

How is the Iranian establishment reacting here?

I mean, are we seeing signs that this is proceeding in an orderly fashion or are there, I don't know, indications of some sort of destabilizing power vacuum that someone else might try to sweep into?

I mean, we've seen the CIA had assessed that a hardliner could take power in the Ayatollah's absence.

I mean, is it safe to say we're not seeing regime change per se?

The regime is just finding someone new to take the place of the Ayatollah?

President Trump said last night that Iran's entire military command is gone, adding as well that many of them want to surrender.

Those are Trump's words there.

Do we see any indication of that?

Just at least in terms of the pace of attacks that we've been witnessing, clearly someone is making military decisions still and a lot of them.

I've been speaking to Wall Street Journal correspondent Suna Rasmussen.

Suna, thank you as always.

Thanks for having me.

Coming up, we'll look at the market impact of the conflict as some investors predict we could see $100 a barrel oil this week.

That and the rest of the day's news after the break.

Oil prices are surging as strikes on ships in and around the Strait of Hormuz have thrust one of the world's key choke points for energy into the crossfire.

Natural gas prices have also jumped, and investors wary of a wider conflict in the Middle East are flocking to safe havens like gold and the dollar.

Iranian officials and media have shared conflicting statements about whether Tehran intends to block sea traffic through the strait, but Dow Jones commodities reporter Julia Petroni says the uncertainty is already having a major market impact.
