Argentina accuses UK of "militarisation" of Falklands

Argentina's foreign minister has accused the UK of sending a nuclear-armed submarine to the South Atlantic, after making an official complaint to the UN over the Falklands dispute.

Hector Timerman demanded that the British confirm the location of nuclear submarines in the region.

But UK officials said the accusations of militarisation were "absurd".
