A map, or chart, used by refugees from Syria and Iraq to get into and through Europe has been found by researchers from the Open University.

Refugees interviewed in Paris told the researchers - who were looking into the use of smartphones on the migrant route - that the map was widely shared using apps such as Whatsapp and Facebook.

The map was revealed as part of an Open University report: Mapping Refugees Media Journeys, external. 

The researchers say there is a "huge gap" in the provision of relevant, reliable and timely news and information for refugees. Instead, they are forced to rely on unreliable sources on social media and exposed to greater risks. 

The report urges the European Commission to fund a partnership between EU states, news organisations, technology companies and NGOs to help come up with a way of providing up-to-date news. 

Sarah Montague was live‬, external in Vietnam looking at how first and second generation Vietnamese are being attracted back to the country. She was speaking to Kien Pham who left Vietnam in the 1970s but came back 10 years ago, and Madame Ton Nu Thi Ninh, who used to be Vietnam's Ambassador to a number of European Countries.

A little earlier, David Goodhart, director of the Integration Hub at the Policy Exchange think tank, highlighted the "conflicted obligations" of people in richer parts of the world to migrants.

"We have an obligation to the desperate of the world but we also have an obligation not to unduly disrupt poor and developing countries by tempting people here, one might say," he told the Today programme.

The UN high commissioner for refugees says the migrants crisis is now a global phenomenon and that simply turning them away "won't work".  

He said the sheer number of refugees globally was now too large for states to simply shut borders and push people away.

"Global displacement, having reached 60 million people... requires a different kind of investment and therefore it involves everybody. Everybody has an interest to stabilise, to reduce flaws in order to make them more manageable, to address the root causes. It's going to be a very long and difficult discussion, but there can't simply be a reaction whereby states shut down borders and push people away simply because it won't work. Human mobility today is stronger than these controls."

Most people reading this know the internet as a place with relatively few limits.

But for hundreds of millions of people, the internet isn't so simple.

Our lives are increasingly lived online, yet so little attention is paid to the invisible borders that prevent people and information from moving freely through the world.

In Iran, where I was born, being gay is a sin, a crime, and the conservative clerics would have you believe it's also a myth.

What's so harmful in the case of Iran is the barriers to accessing information — there are gay people in Iran who don't know that being gay is even a concept.

That's it from our #WorldOnTheMove coverage on the Today programme - but stay with us for more content on Start the Week on BBC Radio 4, and Angelina Jolie Pitt's speech at 12:15 BST. 

We are broadcasting live from Vietnam and the BBC Radio Theatre in London. Stay with us for more coverage examining how the movement of people is changing the world. 

 Mark Williams writes on Facebook:

James Graham, the acclaimed playwright and author of This House, is focusing on domestic UK migration for a special short drama being broadcast on Radio 4 at 14:15 (13:15 GMT). "The movement of people for work is a British invention," he told Today. 

Mr Graham confessed he still had to finish the script for the drama. 

"I should really be writing it and not talking about it," he joked. 

UNHCR Special Envoy Angelina Jolie Pitt will give a keynote address on the global refugee crisis at 12:15 BST (11:15 GMT).

She is expected to say: "Fear of uncontrolled migration has eroded public confidence in the ability of governments and international institutions to control the situation. It has given space, and a false air of legitimacy, to those who promote a politics of fear and separation. 

"This has created the risk of a race to the bottom, with countries competing to be the toughest, in the hope of protecting themselves whatever the cost or challenge to their neighbors, and despite their international responsibilities."

We will have a range of speakers on programmes across the BBC, including Today, the World at One and PM on BBC Radio 4, BBC World Service Radio, BBC World News and the BBC News Channel. Here is a rundown of events planned for the day.

The world is on the move, and much of it coming to live near you. Or so it might seem if you live in northern Europe just now.

But what is the big picture of migration, over decades and across the whole world? And how does what we're seeing today compare?

David Goodhart, director of the Integration Hub at the Policy Exchange think tank, highlights the conflicted obligations of people in the "rich world". 

He told the Today programme: "We have an obligation to the desperate of the world but we also have an obligation not to unduly disrupt poor and developing countries by tempting people here, one might say.

"We don't want to create a wholly unbalanced world in which the most dynamic and best educated people in poor countries find the only way they can have a decent life is by getting themselves into developed European or western countries." 

Tat Wa Lay has returned to Vietnam after living in the UK, like many of Vietnam's 4 million-strong diaspora. 

He says: "It’s nothing to be proud of if you’re from a certain country, it’s no achievement. It’s about what you do for a country [that counts]."

You can read more from Sarah Montague's interview with Tat Wa Lay here. 

Sarah Montague has been speaking to Tat Wa Lay, who was just a baby when his family fled Vietnam for the UK.  

His mother had told him about the moment in 1984 when they arrived on a council estate expecting hostility and racism and instead a "young scruffy man" took off his coat and handed it to the freezing cold refugees.

The gesture was so touching he said that others soon followed. His mother never forgot that moment and he says "my brother still remembers the warmth of that coat and it stays in his heart to this day".

More people are now fleeing conflict and hardship than at any other time in recorded history. 

Many are children and most of them are losing out on their education. Save The Children says only one in four refugee children is now enrolled in secondary school. 

The charity is calling on governments and aid agencies to adopt a new policy framework which would ensure no refugee child remains out of school for more than a month.

It's an ambitious target but there is growing concern that this migration is producing a lost generation of children, which means conditions for even greater insecurity and poverty. 

Today at the BBC, the special envoy for the UN's refugee agency, Angelina Jolie Pitt, will call for strong multi-lateral action to respond to this migration, which she describes as the challenge of our century. 

She'll say there is now a risk of a race to the bottom, with countries competing to be the toughest, despite their international responsibilities.
