Jihadists from the Islamic State group have destroyed ancient sites and museum pieces in Syria and Iraq in the last two years but that is just the latest example of extremists attacking religious buildings or art. Historian Francois Boespflug, a French former Catholic priest, tells AFP about the roots of attacks against images that the perpetrators consider to be blasphemous or idol worship. "Most Christian extremists who act in this way claim they do so because of blasphemy. But this concept of blasphemy has been gradually removed from the criminal law of most European nations." [link]
