Argentine protesters outside British embassy

Masked protesters have torn down a police fence and hurled rocks during a demonstration outside the British embassy in Buenos Aires.

Riot police responded with rubber bullets and water cannons.

The protest came on the 30th anniversary of Argentina's invasion of the Falkland islands which it claims as the Malvinas.

Britain has controlled the Falklands since 1833 but Argentina claims it owns the territory saying it inherited rights to them from Spain.
