Russia submits its claim to Arctic seabed
Russia has submitted its bid for vast territories in the Arctic to the United Nations.
It is claiming 1.2 million square kilometres (more than 463,000 square miles) of Arctic sea shelf, the Russian foreign ministry said.
Russia, the US, Canada, Denmark and Norway have all been trying to assert jurisdiction over parts of the Arctic, which is believed to hold up to a quarter of the planet's undiscovered oil and gas.
Rivalry for Arctic resources has intensified as shrinking polar ice is opening up new opportunities for exploration.
Russia was the first to submit its claim in 2002, but the UN sent it back for lack of evidence. The new bid contains more data.
The ministry said that the resubmitted bid contains new arguments. "Ample scientific data collected in years of Arctic research are used to back the Russian claim," it said.
Russia expects the UN Commission on the Limits of the Continental Shelf to start looking at its bid in the fall, the ministry said.
In 2007, Moscow staked a symbolic claim to the Arctic seabed by dropping a canister containing the Russian flag on the ocean floor from a small submarine at the North Pole.
Amid tensions with the West over Ukraine, the Kremlin also has moved to beef up Russian military forces in the Arctic.
The effort has included the restoration of a Soviet-era military base on the New Siberian Islands and other military outposts in the Arctic.
Russian officials said the facilities are key for protecting shipping routes that link Europe with the Pacific region across the Arctic Ocean.
Earlier this year, the military conducted sweeping manoeuvres in the Arctic that involved 38,000 servicemen, more than 50 surface ships and submarines and 110 aircraft.
As part of the drills, the military demonstrated its capability to quickly beef up its forces on the Arctic Novaya Zemlya and Franz Josef Land archipelagos.
