In Scotland, protesters are demonstrating today outside the meeting of the G8 where President Bush and other world leaders are gathering. Earlier in the day police ordered demonstrators to call off the protests but then reversed their decision after protest organizers gave police an ultimatum to permit the march or face a mass protest in Edinburgh. The BBC reports the G8 summit marks the biggest security operation in the history of Britain. At least 60 protesters have already been arrested today. Scotland has been the scene of a series of demonstrations since Saturday. On Saturday, over 200,000 people took to the streets of Edinburgh. The Indymedia UK website is reporting that earlier today protesters blocked a busload of Japanese delegates from attending the summit.
