More people are fleeing from Syria, Russia and Afghanistan than any other countries on earth, according to a new report from the UN Refugee Agency. For the first time, more of them came from Syria than any other country, around 56,400; more than double the figure for 2012. At least two-and-a-half million people have fled the fighting. And there's no sign of it letting up - government forces are making large gains in the west of the country.
