Many millions of people around the world are displaced, having had to flee their homes to escape persecution or war, or because they left in search of work and a better life. Paul Wood has been to Syria, Iraq and now Lebanon, where the advance of the so-called Islamic State has devastated, and ended, lives. Like that of a young, disabled Yazidi boy, or that of a Lebanese army sergeant.

Caroline Wyatt in the Kurdish city of Dahuk in northern Iraq, finds that many who fled IS further south came here, and that the local authorities are struggling to cope with what they say has become a humanitarian crisis.

Jon Donnison in Australia reports that the mood has turned against migrants and refugees, particularly those arriving by boat. Many are held in detention centres, and documents even showed that the Australian authorities are working with the embassy of Syria's President Assad, potentially with the view of returning Syrians to the dangers they had escaped from.

Linda Pressly visits a Guatemalan drug rehabilitation centre, where she meets a detainee - as they are - who moved to California with his parents as a boy, escaping Guatemala's civil war. But he ended up being deported, and an attempt to return to the US failed.
John Murphy on the island of Achill off Ireland's west coast finds that so many people have left to find work elsewhere, that it is now hard to get a football team together. For a recent match, three players had to fly back from the UK and Sweden to make up the numbers.
