The protest was held to mark 20 years since the unsolved bombing attack against a Buenos Aires Jewish center that left 85 dead. Prosecutors blame Iran for the attack. The hashtag reads in Portuguese “One minute for the AMIA,” which stands for “Israeli Argentine Mutual Association,” the Jewish community center of Buenos Aires. (AP Photo/Dario Lopez-Mills)
