Hello and welcome to NewsHour live from the BBC World Service in London.
I'm Rebecca Kezby.
And we begin the programme in the south-east European country of Bosnia-Herzegovina,
where today thousands drew together to mark a very solemn anniversary.
It's 30 years since the Srebrenica massacre,
the worst single atrocity on European soil since World War II.
It took place during the Balkan Wars of the 1990s,
after the old socialist state of Yugoslavia broke up,
populist leaders weaponised ethnic differences,
and a complex civil war broke out between three different groups,
Serbs, Croats and Bosniaks, which are mostly Muslim Bosnians.
War crimes were carried out by all sides,
and the traumatic echoes of those are still felt to this day,
but the Srebrenica massacre has been legally recognised as a genocide.
Around 8,000 people, mostly Bosniak boys, and men were first rounded up by the Bosnian Serb forces.
That captured in the archive there
while they were then separated from their families and systematically murdered.
What's also shocking is that this happened in a designated safe area that UN forces were supposed to be protecting.
There's still around 1,000 people unaccounted for,
their bodies have not yet been found and today the recently discovered partial remains of seven victims were laid to rest alongside other victims.
