Thousands march through Buenos Aires on Tuesday, March 24, on the Day of Remembrance for Truth and Justice - the 50th anniversary of the 1976 coup d'état; a takeover which led to a period of military rule.

On March 24, 1976, Argentina’s military overthrew elected president Isabel Perón, arresting her and installing a junta led by Jorge Rafael Videla.

Demonstrators gather in the capital’s main square, caring photos of victims of the so-called 'Dirty War' - when an estimate 30,000 people were 'disappeared'. Organisations such as the Mothers of the Plaza de Mayo are due to take part, demanding more accountability and safeguarding of the historical record.

The regime, which ruled until 1983, is widely regarded as one of the most brutal in Latin America’s history.
