There's thousands of people fleeing their homes in the Middle East at the moment because of extremists taking over. They're normal families just desperate for a safe home. Some Islamic State militants claim to have hidden themselves in amongst the genuine refugees too. And there are also several economic migrants who are just trying to find a better life but aren't actually fleeing any danger. How much should we and governments help? And what should we do?
