Stephen Sackur asks Lord Dubs: "Do you see a change amongst us humans? Do you think we are more compassionate or less compassionate today than we were in 1939?"

"I'd like to think we're more compassionate," Lord Dubs says, because we see more about crises on our television screens. "Equally, we seem to have more concerns about migration."

However, Lord Dubs says he believes the British are still very compassionate. 

Dadaab was meant as a temporary home for Somalis fleeing their country's civil war. Twenty five years later, it's home to 330,000 people - and the third biggest city in Kenya. This week, the Kenyan government announced plans to try and close it down.

The international human system that deals with refugees is so "broken" that the UN has called a summit to address it.

But how did things get so bad? The BBC explains the numbers behind the headlines.

James Graham's short drama for Radio 4 tried to show the "movement of people" is not just a distant, global phenomenon but something that is affecting many young people in the UK. You can still catch up and listen to the play.

Uganda has been praised for having some of the world's most welcoming policies towards refugees, the BBC's Catherine Byaruhanga reports.

Khadija al-Hassan, who fled fighting in Somalia six years ago, likes her life there. "There is no problem in Uganda. Refugees are given houses, food and free education for their children. You can even sleep in the open and no-one will bother you."

At the heart of this generosity may be that many people in power know what it is like to be forced to flee. Thousands of Ugandans were refugees in the years after independence in 1962 - even President Yoweri Museveni and some of his cabinet colleagues have been exiles themselves.
