He spoke at a memorial service shortly after sirens sounded at 9:53 a.m. on Thursday to mark the moment of the attack a quarter century ago.

Argentina added Hezbollah to a new, publicly available registry of entities or people who could be tied with terrorists, a list based on information provided by the United Nations, by the country’s judiciary and by the Financial Information Unit, or UIF, Argentina’s anti-money laundering organization.

Hezbollah “continues to represent a current and present threat to national security and the integrity in the Argentine Republic’s financial economic order,” the UIF said in explaining its inclusion of the group in the new registry.

“This is a very useful tool that reinforces our legal framework to prevent future actions related to terrorism and its financing,” Justice Minister Germán Garavano said. He also said the move has a “symbolic value,” considering that Argentina’s judiciary has also accused members of Hezbollah and the Iranian government of taking part in the community center attack as well as a 1992 bombing of the Israeli embassy in Buenos Aires that killed more than 20 people.

There are currently five Interpol red alerts for Iranian citizens and three for Lebanese citizens that the Argentine courts have accused of taking part in the community center attack. Iran has long denied any involvement.

A quarter century after the attack, the Argentine judiciary has yet to criminally convict anyone for carrying out the assault. Earlier this year, eight people, including a former federal judge and a former head of the intelligence services, were convicted of taking part in a cover-up to obstruct the investigation into the 1994 bombing.

Last year, the Financial Information Unit ordered the freezing of the assets of the so-called Barakat Clan, which is considered the most direct connection with Hezbollah in the region. The clan operates from the porous tri-border region where Argentina, Brazil and Paraguay meet, an area seen as a hub for illegal activity, including terrorism financing.
