From the BBC:

Argentines have been marking the anniversary of the 1994 bombing of a Jewish centre in Buenos Aires that left 85 people dead and about 300 injured…. A prosecutor last year blamed Hezbollah for the blast, which the group denied….

The blast on 18 July 1994 reduced the seven-storey Jewish-Argentine Mutual Association (AMIA) community centre in Buenos Aires to rubble.

The scale of death and destruction left Argentina's 200,000-strong Jewish community, Latin America's largest, in shock….

Local Jewish groups have long said the bombing bore the hallmarks of Iranian-backed Islamic militants.

Iran has repeatedly and vehemently denied any involvement in the attack.

Last November, an Argentine prosecutor said a member of the Islamic militant group, Hezbollah, was behind the attack and had been identified in a joint effort by Argentine intelligence and the FBI.

But Hezbollah said that the man, Ibrahim Hussein Berro, had died in southern Lebanon while fighting Israel.
