Extinction Rebellion protesters attempt to block traffic on Fleet Street in London. The group said it will begin a week-long "summer uprising" in Bristol, Cardiff, Leeds, Glasgow and London. Protesters in each city are unveiling a large coloured boat, each named after an environmental activist, with the message "Act Now" on it. The activists say they are staging a series of "creative acts of civil disobedience", blocking specific locations, bridges and roads as well as holding talks, workshops, people's assemblies and family-friendly activities. In Glasgow, activists are using a 25ft purple boat to block Trongate, covering the intersection of Gallowgate and High Street, by the Merchant City clock tower.
