[Migrants who will be returned to Turkey demonstrate inside the Moria registration centre on the Greek island of Lesbos]By Gabriela Baczynska BRUSSELS (Reuters) - The European Commission proposed more unified EU asylum rules on Wednesday, in a bid to stop people waiting for refugee status moving around the bloc and disrupting its passport-free zone. In an unprecedented wave of migration last year, 1.3 million people reached the EU and most ignored legal restrictions, trekking from the Mediterranean coast to apply for asylum in wealthy Germany, prompting some EU countries to suspend the Schengen system that allows free passage between most EU states. "The changes will create a genuine common asylum procedure," said EU Migration Commissioner Dimitris Avramopoulos.
