Europe and Britain must offer asylum to those genuinely fleeing persecution but also need to boost aid, defeat smuggling gangs, and tackle the conflict in Syria to stem a migrant crisis, Britain's finance minister told Reuters on Saturday."It's absolutely clear we need a comprehensive plan across Europe," Osborne told Reuters on the sidelines of a meeting of G20 finance chiefs in Turkey."Yes, we must offer asylum to those who are genuinely fleeing persecution. Countries like Britain always have, we are one of the founders of the asylum system. We will take, as the prime minister said, thousands more," he said."But at the same time, you've got to make sure you've got aid going into the refugee camps on the borders ... We've got to defeat these criminal gangs who trade in human misery and risk people's lives and kill people."
