Iran said on Sunday Israel's treatment of the Palestinians constituted a greater crime than the Holocaust, the latest in a series of remarks suggesting the genocide was exaggerated to boost Israeli interests. "I believe the crimes committed by the Zionist regime are greater than the Holocaust," Foreign Ministry spokesman Hamid Reza Asefi told a news conference. "Unfortunately, the Zionist regime is blackmailing the Europeans with the Holocaust," he was quoted as saying by Reuters.
