Negotiations between protesters and police in Rexton, N.B., on Oct. 17, 2013. The clash between the RCMP and the Elsipogtog First Nation, north of Moncton, began early Thursday morning when a large number of officers arrived at a compound where SWN Resources Canada stores equipment. The police intended to enforce an injunction against a native blockade that has prevented SWN, a natural gas and oil exploration company, from conducting seismic testing.ANDREW VAUGHAN/The Canadian Press
