Aug. 2 - Russia has planted a flag on the seabed directly under the North Pole in a move seen as a symbolic claim on the resource rich region
Canada dismissed the move, saying the tactic was more suited to the 15th century than the real world.
Canada is one of five states with territory inside the Arctic Circle.
Under international law the five, which also includes the U.S. Denmark and Norway, have a 320 km (200 mile) economic zone beyond their land borders.
But Moscow is hoping to establish that Russia and the North Pole are part of the same continental shelf, which could allow Russia to claim sovereignty over the energy-rich region.
