Protesters in Argentina have clashed with riot police outside the British embassy on the 30th anniversary of the Falklands war.

Argentina claims the British-ruled islands in the South Atlantic Ocean, and calls it Malvinas.

Cristina Fernandez Kirchner, the Argentine president, has recently stepped up a diplomatic offensive against Britain.

Her government has tried to get the backing of Latin American nations in its claim and has also tried to take economic measures to isolate the Falkland Islands.
