Hello and welcome to News Hour from the BBC World Service.
Coming to you live from London, I'm Krupa Bhatti.
Thanks for being with us.
Coming up later in the programme.
The end of the road for the Danish Postal Service.
But what will happen to those who still want to write a letter?
Plus, a new search is underway for the Malaysia airline flight MH370 that went missing 12 years ago.
Imagine you put a bus somewhere in Wales and you're going to look for that bus.
That's the challenge in itself, but imagine doing that with your eyes closed.
That all coming up later in the program.
But first we begin with an escalation with the war in Yemen, often called the world's forgotten war.
Almost five million people have been forced from their homes.
Over 18 million are in need of humanitarian assistance and hundreds of thousands have been killed.
It can be tricky to understand the dynamics of this war and who controls what in Yemen.
So let's try and map this out simply before getting the very latest.
Yemen is at the southern tip of the Arabian Peninsula and it's been embroiled in a civil war for over a decade now between the Iranian-backed Houthis in the West and the internationally recognised government known as the Presidential Leadership Council,
or PLC, elsewhere in the country.
The PLC is backed by Saudi Arabia, which shares a long border with Yemen,
and the United Arab Emirates also joined the Saudi-led military coalition against the Houthis in 2014.
But a UAE-backed faction has now taken control of Yemen's south, pushing out Saudi Arabia's allies.
