Twenty activists donned suits and ties and buried their heads in the sand on a Scottish beach Saturday to protest against a meeting of finance ministers from the Group of 20 powerful nations. The protest on West Sands, where beach scenes in the 1980s Oscar-winning movie “Chariots of Fire” were filmed, began a peaceful march that attracted more than 200 people. Demonstrators will be holding a rival People's G20 in St Andrews, a few miles from the hotel where finance ministers and central bankers of the world's most powerful developed and emerging nations are meeting to discuss the global economy. To prevent suffocation, the protestors from environmentalist and other groups buried buckets in the beach and then stuck their heads into them. Police were on the streets of St Andrews in large numbers on Saturday to deal with any potential violence later in the day. A second demonstration, which will bring St Andrews students and residents together with anti-war and socialist groups, will start in the town and march towards the resort where the G20 officials are meeting.
