Protesters have clashed with police in Athens as huge demonstrations take place across Greece, marking two years since the country's worst ever train crash.
President Zelensky prepares to meet President Trump at the White House with a minerals deal on the table.
Europol says it's made dozens of arrests in a large -scale operation against AI -generated child sexual abuse material.
Also in this podcast, a Japanese documentary about a rape case is aiming for the Oscars, despite not being shown in Japan.
I want to break the idea of perfect victim, because that was what was stopping me.
People telling me you're not lying enough talking to the policemen.
We start in Greece.
Hundreds of thousands of people have been protesting in towns and cities across the country to mark two years since a rail disaster that killed 57 people.
In Athens, hooded protesters threw petrol bombs at police.
There were clashes outside Parliament as officers tried to disperse the crowds with tear gas.
The crowd say they want justice for the 57 people who were killed when a passenger service collided with a freight train near the Tempe Gorge in 2023.
A report published on Thursday found the crash was caused by human error, poor maintenance and inadequate staffing.
And protesters like these two are venting their anger.
We want to send the message to the government and the employers that we will not tolerate anymore, going to work and not knowing if we are going to get back home alive.
I came here for justice in order to finally find out why so many young people were lost, to finally find out why there are accidents that put lives at risk every day.
That time it was those children, but it could have been my own kid.
I heard more from our reporter in Athens, Helena Smith.
We've seen extraordinary scenes here in Athens today.
First of all, an incredible demonstration in the square that is the site of the Greek Parliament.
Tens of thousands of people gathered there in a first.
They weren't chanting themselves hoarse.
They were silent, most bending their heads in honour of the dead.
this is the anniversary, the second anniversary of the country's worst ever rail disaster that saw 57 mostly young students die in an accident that many in Greece believe was entirely preventable and is down to systemic failures, the failure of the state to provide even basic services like a modern
railway system. You mentioned that it's been silent and mournful, but there's also been violence.
That's absolutely right.
Barely had the relatives of the victims finished addressing the crowds when clashes erupted across the square in what appears to have been a very well coordinated plan to disrupt an otherwise peaceful protest.
with black -clad, hooded youths emerging, throwing rocks at riot police, Molotov cocktails, etc.
And within minutes, thousands of people found themselves fleeing the square, some even taking refuge in the Greek parliament as the air became filled with this acrid tear gas fired by riot peace.
And then, of course, the crowds, but we're talking about tens of thousands of people, disperse.
we're at the tail end of that happening but much of central Athens has been turned into a war zone pitch battle between riot police and these rock lobbying youths.
There have been extraordinary scenes even around the Greek parliament with youths throwing Molotov cocktails, setting off fires in the courtyard of the Greek parliament.
The report on Thursday which suggested there are still a lot of failures haven't been rectified.
Have the authorities given any indication that they are going to act on this and perhaps assuage some of the protesters' concerns?
Well, the government has said that it will act on this, that its plan is to create a modern railway system, but it's been very slow.
What has stoked so much of this public outrage here in Greece is this sense of a government cover -up and that in the days after, the state moved very, very quickly to clean up the scene of the tragedy, removing what could have been very vital evidence, including, if you can believe it, human remains,
from the site of the crash by gravelling and cementing it over.
None of that has helped assuage this public sense that somehow they're not being told the truth.
Helena Smith in Greece.
To the United States now.
And as we record this podcast, the Ukrainian President Volodymyr Zelenskyy is preparing to meet Donald Trump at the White House for a crucial encounter.
They'll be discussing how to end the war that began with Russia's invasion.
And at Mr Trump's insistence, they're set to sign a deal that would open up Ukraine's vast mineral wealth to the US, but with no American security guarantees for Ukraine in place.
Lisa Yasko, an MP from the Ukrainian President's Servant of the People Party, is nevertheless optimistic.
It looks like the deal looks not bad and quite good for Ukraine, not only for the economic interest in general, but also for the future.
Because for us, it is very important that hopefully one day the war is over, that there will be different projects, different reconstruction, big projects that will...
