'Goodbye Spain': Huge rally for Catalan independence before vote

Hundreds of thousands of Catalans rallied on Monday to demand their region's secession from Spain, in a show of strength three weeks ahead of an independence referendum which has been banned by Madrid.Draped in red, yellow and blue separatist flags -- with one banner reading "Goodbye Spain" -- they marched through central Barcelona in what many hope will be the last protest before independence.Around one million people took part in the event, Barcelona's municipal police said in a Twitter post.
