Russian explorers dived deep below the North Pole in a submersible on Thursday and planted a national flag on the seabed to stake a symbolic claim to the energy riches of the Arctic.

A mechanical arm dropped a specially made rust-proof titanium flag onto the Arctic seabed at a depth of 4,261 meters (13,980 ft), Itar-Tass news agency quoted expedition officials as saying.

Russia wants to extend right up to the North Pole the territory it controls in the Arctic, believed to hold vast reserves of untapped oil and natural gas.
