Refugees are displaced persons who have been forced to cross national boundaries and who cannot return home safely. Such a person may be called an asylum seeker until granted refugee status by the contracting state or the UNHCR if they formally make a claim for asylum. Now, the numbers and refugee camps are growing all over the world with millions of people living in extreme poverty.
Camp Moria, on the Greek island of Lesbos, was built for 2500 refugees. It now holds 8000, and aid organizations often criticize conditions there. Now refugees there claim that a violent gang affiliated with the so-called Islamic State has taken over.
Turkey has taken in more Syrian refugees than any other country. Now it has built a wall to keep any more from crossing the border, and is trying to help them on the Syrian side instead. That job has fallen to aid organizations like the Red Crescent.
