Argentina protests as William arrives in Falklands Argentine demonstrators have attacked a branch of the British bank HSBC in Buenos Aires to protest against Prince William's arrival in the Falkland Islands. The demonstration was organised by the extreme-left Quebrancho movement amid heightened tension between the two countries over sovereignty. It is almost 30 years since Britain retook the islands by force following an Argentine invasion. This is in response to the presence in Argentinian territory of the pirate Prince William. What we are doing here is paying homage to those fallen in the Malvinas war, here at the cenotaph that commemorates them," said protest leader Fernando Esteche. From here we will call on to the entire Argentinian nation to join us, and we will develop our campaign to thwart that of the English. The Duke of Cambridge is beginning a six-week deployment as a search and rescue helicopter pilot. Britain, which has held the islands in the South Atlantic since the 1830s, has dismissed Argentina's claims that the move is provocative and political. Buenos Aires has criticised what it calls a British attempt to "militarise conflict." London also insists a new warship due to be sent to the region is a routine deployment to replace a frigate already there.
