Demonstrators surround a large banner with portraits of people disappeared in the 1976-1983 military dictatorship during a gathering to commemorate the 39th anniversary of the coup of 1976, at Plaza de Mayo Square in Buenos Aires on March 24, 2015. About 30,000 people went missing after being arrested during the right-wing military regime that ruled Argentina from 1976 to 1983, according to Human Rights organizations. Many of those abducted were accused of being leftist sympathizers or deemed subversive by the regime. AFP PHOTO / JUAN MABROMATA (Photo credit should read JUAN MABROMATA/AFP/Getty Images)
