An adviser to Iran's supreme leader has dismissed accusations that he masterminded Argentina's worst terrorist attack, saying in an interview that he and the Islamic Republic are innocent.

Ali Akbar Velayati, who was foreign minister of Iran at the time of the 1994 bombing of the AMIA Jewish community center in Buenos Aires, is now an adviser to Ayatollah Ali Khamenei.

Former Iranian officials have been on an Interpol capture list for years, but Argentine prosecutors have never been able to question them. Iran has long denied any role in the unsolved bombing that left 85 people dead.
