Award-winning playwright James Graham's radio drama on migration will be broadcast live at 14:15 on Radio 4. This morning, he said he hadn't finished the play yet - here's hoping it's complete by now!

Read the BBC News website's coverage here of Angelina Jolie Pitt's speech, in which she warned that the established system of dealing with refugees over recent decades was 'breaking down'.

That's it from Angelina Jolie Pitt's keynote speech. Stay with us for more reports on #WorldOnTheMove, and visit our Facebook page to watch the video again. 

"This is a time we can come out stronger and better - but it takes clarify and leadership," she says. Solving the refugee crisis is "something we all know we must do," Jolie insists.

Mishal Husain asks whether German Chancellor Angela Merkel's response to the crisis, where she said all Syrian refugees were welcome, was pragmatic or based on emotion.

Jolie says: "It was a beautiful, beautiful thing that said something to the world. But I do think we need to have a real order, and we need to be explaining how things are being done in a clear way."

It is also important that the process is clear so that people in the receiving country understand and have better confidence in the system, she says.

Here are some of the comments we’ve received on our Facebook page, external:

Hasnain Sayied: She is doing what good people dream of doing all their life… speaking truth, stand for those who need help, actually help, may God bless her and giver her long and healthy life.

Holly Marston: She has the right intention but is still frustratingly vague. Certain people and governments need to be named and made accountable and specific reforms that are needed to enable progress.

Genia Goncharenko: A reasonable and passionate speech of a beautiful and a decent woman, but the problem is that those who can change the situation are actually creating all those dreadful conditions.

A 12-year-old has a question for Jolie: "Do you have any ideas about how we can support young people coming into our community?"

Jolie Pitt: "The best thing you can do, especially at your age - school's hard regardless, fitting in, isn't it? The best thing is to be a good friend, ask about their culture, where they came from. Help others around you - maybe you see some bullying, people not understanding or showing respect - but you can set an example and give them the welcome they deserve."

Yvette Cooper, a UK Labour MP, asks about protection for child refugees.

Jolie Pitt: "More than half of the refugees are women and children; half of these children are out of school."

Many children have faced abuse or trauma, she says, and we need to ensure they have enough support.

"We have to look at the ways they are being held" as well, she says.

Unaccompanied children are also a serious concern, and trying to keep families together or ensuring children are accompanied by an adult or a sibling, rather than being left open to trafficking, is important - she adds. 

Jolie is asked if she's disappointed by Republican presidential hopeful Donald Trump's approach on refugees and Muslims. 

"America is built on freedom of religion," she says, so "it's hard to hear that this is coming from someone who is pressing to be president".

David Davis MP, a conservative UK member of Parliament, asks:

"You recognise the need to go to the source of the problem - after the second world war, the US went to the source of the problem with the Marshall plan. Is there a chance the US will go to the source of the problem again?"

Jolie: "All I can say is they absolutely should, and they'd better. They have to work with countries around the world, as before - that is what they must do. As an American I will be pressing my government about it - I have been very disheartened by my own country's response to this question."

"When people are not in a country at war, but are being persecuted, or attacked because of their ethnicity, etc - these are reasons for people to be granted asylum."

Therefore, it is important not to make blanket distinctions, Angelina Jolie Pitt says.

Jolie Pitt is asked: Is the distinction between economic migrants and refugees unhelpful? How can you determine the difference in complex countries, such as Afghanistan?

She replies that the desire for a better life is admirable, and she might do the same thing in their situation. But refugees are "running for their lives - it's immediate and urgent".

Because of this, refugees "should be put forward first".

Angelina Jolie Pitt: "Some people are pushing to pass by that process and not get registered, and this is bad for everybody... it's the responsibility of refugees, migrants and governments to make sure the process is done well." 

Watch as Angelina Jolie warns that the refugee crisis has created a "race to the bottom" with countries competing to be the toughest on immigration.

Mishal Husain asks: "Can you understand why people around the world might not feel welcoming?"

Jolie Pitt: "Yes, when it's not explained to you, when you have media and politicians preying on that fear."
