A prosecutor sought the arrest of former Argentine President Carlos Menem, accusing him of covering up the involvement of a Syrian-Argentine businessman in a 1994 bombing that killed 85 people at a Jewish center in Buenos Aires.
The former president denied the allegations.
Prosecutor Alberto Nisman also requested the arrests of Menem's brother, Munir, and four other men. As a senator, Menem is immune from prosecution, but Nisman asked that the privilege be revoked.
The prosecutor said in his petition to Judge Ariel Lijo that Menem and his aides tried to cover up the possible involvement of Alberto Jacinto Kanoore Edul in the bombing.
Argentine prosecutors accuse Iranian officials of organizing the bombing, but they also say Argentines were involved.
