Argentine Jewish leaders are opposing a deal with Iran that President Cristina Fernandez sent to congress Friday for approval.

Fernandez says it will advance a criminal investigation of Argentina's worst terrorist attack - the 1994 bombing at a Jewish center that killed 85 people.

The deal calls for a "truth commission" and allows for Argentine prosecutors to question Iranian suspects in Teheran.

Jewish leaders Guillermo Borger and Julio Schlosser say they worry that those responsible could be let off the hook.

The deal limits questioning to five suspects named in Interpol alerts, including Iranian Defense Minister Ahmad Vahidi.

Schlosser says that leaves out other suspects too high-ranking to be targeted by Interpol: former Iranian President Akbar Hashemi Rafsanjani, former Foreign Minister Ali Akbar Velayati and former Ambassador Hadi Soleimanpour.
