The attack took place on the morning of July 18, 1994. A car bomb destroyed the AMIA, (Asociacion Mutual Israelita Argentina), a Jewish community centre in Buenos Aires, leaving 85 dead and 300 wounded.
It was the deadliest terrorist attack ever in Argentina's history and came just two years after the 1992 bombing of the Israeli Embassy there.
An official Argentinean government report in 2006 identified Iranian and Hezbollah figures as responsible for the attack but to-date no one has been brought to justice.
'Count on me', the Pope told them during the meeting. He encouraged them to continue their efforts because 'this is the only way' and 'it is necessary to arrive at the real truth as quickly as possible, which will take us to justice'.
It is 'only in this way that you can have the peace you seek', he told them.
At the time of the bombing, the then-Bishop Bergoglio was an auxiliary in Buenos Aires, but he was the first public figure to sign a petition condemning the attack and calling for justice.
Leaders of Argentina’s 250,000 Jews - most of them live in Buenos Aires, consider him a friend and are grateful for his solidarity then and his ongoing support.
Jewish community leaders around the world noted that his words and actions "showed solidarity with the Jewish community" in the aftermath of that deadly attack.
