Faslane, Scotland - Protesters shut down a Trident's nuclear submarine base by breaching the outer security perimeter in a surprise demonstration. 12 anti-nuclear campaigners forced the HM Naval Base Clyde to temporarily close for the second time this year, before being arrested. Demonstrators plan to return in far greater numbers on Monday July 4 on the eve of the G8 summit in nearby Gleneagles, Perthshire.
