Leaders in Argentina and Britain have participated in events commemorating the start of the war both countries fought over the Falkland Islands 25 years ago.
Argentina, which launched a failed military attempt to seize the Falklands on April 2, 1982, said Monday it would continue trying to win control of the islands, which it calls Las Malvinas.
Vice President Daniel Scioli said the islands have always been Argentine and always will be. Scioli made his remarks in the city of Ushuaia during an event marking the start of the war.
In the United Kingdom, Prime Minister Tony Blair met with veterans of the conflict aboard a British warship. Margaret Thatcher, the prime minister during the Falklands war, laid a wreath at London's Saint Paul's Cathedral to remember the Britons killed during the conflict.
The death toll from the 74-day war included 655 Argentines, 255 Britons and three islanders.
On Sunday, British Foreign Secretary Margaret Beckett issued a statement expressing "continuing regret" over the deaths suffered by both sides in the conflict. She said the Falkland Islands government and Britain would invite family members of the dead Argentines to hold a memorial service on the islands later this year.
