Israel is denying a claim by its former ambassador to Argentina that Israelis killed most of those responsible for the South American county's worst terrorist attack.

Itzhak Aviran said "the great majority of the guilty ones are already in the other world, and it was we who did this." He also said that Iranians "were the main ones responsible" for the 1994 Jewish cultural center bombing that killed 85 people.

Aviran could not be reached Friday to explain his claims, which Argentina's Jewish News Agency published the day before.

In Israel, Foreign Ministry spokesman Yigal Palmor called them "complete nonsense."

Prosecutor Alberto Nisman said he's asking for the governments to order an Israeli judge to make Aviran explain who was killed and what proof he has.
