Obama to mourn Argentina coup victims as US ponders its role

BUENOS AIRES, Argentina (AP) — Confronting a dark chapter in Latin America’s history, President Barack Obama will pay tribute to victims of Argentina’s “Dirty War,” as he works to bring closure to questions about the U.S. role in one of the region’s most repressive dictatorships.

This week marks the 40th anniversary of the 1976 coup that opened a period of military rule still haunting Argentina. Thousands of people were killed or disappeared.

Closing out his South America trip, Obama plans to use his visit to Remembrance Park in Buenos Aires to lay the groundwork for the U.S. to come clean about any involvement. Though much remains unknown, rights groups believe U.S. backing for authoritarian regimes in Latin America extended to Argentina during the 1976 to 1983 period known as the “Dirty War.”
