22 years after the car bomb attack against a Jewish community center in Buenos Aires, which killed 85 people and wounded hundreds, Argentina's President Mauricio Macri and senior members of his Cabinet attended an annual commemoration ceremony.

Instead of placing flowers at the memorial in the courtyard of the AMIA/DAIA building, as was initially envisaged, Macri chose to participate in the traditional ceremony outside the Jewish center, which is located in downtown Buenos Aires.

It was the first time in five years that an Argentine head of state attended the ceremony.

‘'Memory unites us’’ was the motto of this year's ceremony, which again included the reading of the names of the 85 people who were killed in the July 18, 1994 attack.

Argentine prosecutors believe Iran masterminded the terrorist attack, the worst in the history of Argentina, but no one has been convicted in the attack, which many Argentines believe has come to symbolize an inept and corrupt justice system. .

AMIA Vice President Ralph Thomas Saieg said: "There is an obligation to tell what happened. The terrorists who planted the bomb wanted to destroy the symbol for solidarity that is the AMIA and thus hurt us all as Argentineans."

Saieg called on the country's Justice Minister, German Garavano, to make progress with the investigation.

Survivors also criticized previous governments for not solving the crime. "The justice they deserved is as dead as them," Sofia de Guterman said about her daughter, Andrea Guterman, and other victims during the ceremony held at the reconstructed building. If those responsible don't face justice, "we'll soon have to issue a death certificate for the case itself," Guterman said.

"It's been 22 years of not knowing what went on as a result of badly introduced evidence, other evidence that hasn't even been considered, and documents that the executive power hid from judges," Mario Cimadevilla, head of a special investigative unit focused on the attack, told Argentine radio.

A "truth commission" deal with Iran was denounced by Israel and world Jewish groups, who called it a diplomatic win for Tehran that offered no benefit to Argentina. The deal, which was struck down by a federal court, would have let Iran review Argentina's investigation into the bombing.

During the ceremony, some also called for answers in the mysterious death of the leading prosecutor investigating the case. Alberto Nisman was found dead in his apartment in 2015 with a .22-caliber pistol by his side, one day before he was due to present his case to Argentina's Congress.

Nisman was scheduled to present allegations that then-President Cristina Fernandez orchestrated a secret deal to cover up Iranian officials' alleged role in the attack. Fernandez denied the allegations, and judges later threw out the case.

In 2006, an official Argentine government report prepared by Nisman identified Iranian and Hezbollah figures as responsible for the attack. Interpol issued red notices for the capture of six suspects, including Ahmad Vahidi, a former Iranian Defense Minister.
