I'm Andrew Peach and in the early hours of Monday the 23rd of February these are our main stories.

Violence has broken out across Mexico after the leader of one of the country's most feared drugs cartels was killed in a military operation.

There's been a second day of protests at Iranian universities with crowds chanting death to the dictator.

And a man who broke into President Trump's Mar-a-Lago estate carrying a shotgun and a fuel can has been shot dead.

Also in this podcast, Ukraine's president tells BBC News that Russia has already started World War III.

We have different views regarding a third world war.

I believe that Putin has already started it.

The question is how much territory he will be able to seize and how to stop him.

And the Winter Olympics have come to an end at a glittering ceremony in Verona.

We start in Mexico, where a government military operation has led to the killing of a major drugs kingpin, leader of the feared new generation Calisco cartel.

Nemesio Oseguera Cervantes was known by his nickname El Mencho, a drug lord so powerful the US authorities put a $15 million bounty on his head.

Since his killing, the response from El Mencho's cartel has been swift and violent.

In as many as eight different Mexican states, the group has set cars alight, built roadblocks and attacked security forces.

Plumes of smoke have been filmed rising over several cities and many international flights have been cancelled.

Our correspondent in Miami, Luis Fajardo, told me more about the drug's lord.

That's interesting.

I was going to ask you why now?

And is it about trying to maintain good relations with Donald Trump?

And why are we seeing people all over the country setting cars on fire, building roadblocks, all that kind of thing?
