This is the Global News Podcast from the BBC World Service.

I'm Alex Ritson, and at 14 hours GMT on Sunday 1st March, we're looking at the continuing fallout from US and Israeli strikes on Iran.

The country has come under attack for a second day following the death of the Iranian Supreme Leader Ayatollah Ali Khamenei.

Many Iranians have been celebrating the demise of the man they blame for thousands of deaths despite an official declaration of mourning.

In this edition, we'll hear the latest from the strikes in Iran and Tehran's strikes on Israel and across the Middle East.

We'll ask what legal basis President Trump had to launch these attacks and how it's being seen by his supporters and rivals.

And we'll find out what happens next in Tehran now that the regime is without its supreme leader.

In the last edition of the Global News podcast, we reported that Iran's supreme leader, Ayatollah Ali Khamenei, had been killed in his office in the first wave of US-Israeli strikes on Saturday.

In the hours since then, loud explosions have again been heard across Tehran as Israel maintains its operations against the Iranian capital.

Many Iranians inside and outside the country celebrated the news that the man who held absolute power for 40 years was dead.

but others mourned his death, including these people on the streets of the Iranian capital.

Several high-ranking officials were also killed in Saturday's attacks.

The Israeli military named seven senior Iranian defence officials among the dead.

The Iranian president, Massoud Peseshgian, said the killing of the Ayatollah was a declaration of war against Muslims and said it was Iran's legitimate duty to avenge him.

Our Middle East analyst, Sebastian Usher, told me just how significant a moment this is.

Gauging the mood in Iran is difficult during these extraordinary times in the history of the Islamic Republic.

The country is under an almost total internet blackout and few Western journalists are allowed into Iran.

But we are seeing reports of casualties in the country.

The Iranian Red Crescent says more than 200 people have been killed and more than 700 injured in airstrikes.

State media has reported that strikes killed at least 148 people at a school in southern Iran, including children.
